Let’s see what information is available when Here are two graphs of you look at these graphs of enzyme activity. In the next few slides you will review all the basics of this topic. g p enzyme activity. What do you notice right away? 100 100 30/66 Enzyme reaction rate 0 10 20 30 40 50 60 Cº Enzyme reaction rate 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 pH Page 16 DAT Biology Rapid Learning Series - Tutorial 01 © Rapid Learning Inc.

And that rate is effected by substrate concentration. You also see that half the maximum velocity is a constant called Km. Km is the substrate concentration when the enzyme reaches ½ max velocity. Page 17 DAT Biology Rapid Learning Series - Tutorial 01 © Rapid Learning Inc. All rights reserved. :: http://www.RapidLearningCenter.com 17 Enzyme Denaturation Okay, now let’s take a look at all three graphs together and see what you have learned and equally importantly what you can “discern” about enzymes from just th h Enzyme reaction 100 From the enzyme vs. temperature or pH, we can see that the enzyme max rate drops to zero after the peak with increasing pH or temperature. From this you know that the these graphs. rate 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 pH 100 33/66 y enzyme is no longer functioning is denatured. Enzyme reaction rate 0 10 20 30 40 50 60 Cº Michaelis-Menten Kinetics You have learned that at saturating substrate velocity is constant. And that Km is a constant and How did you know that? Because Rapid Learning uses information dense V )→ 100 V max No loss in activity at ½ Vmax is the substrate concentration where the enzyme is at half velocity. visuals with the level of detail and precision required to do well on the DAT. 34/66 However at saturating substrate concentration the enzyme rate stays constant and does not decrease or increase. So the enzyme must still be working and at a constant rate.

PRACTICE, PRACTICE, PRACTICE Review Material Repeatedly Do Practice Problems Manage Time DAT Preparation Strategy Practice, Practice, Practice Review “mastered” material regularly. Make it part of your long term memory! Layout your review areas and make a schedule. Stick to the schedule. 35/66 Repeatedly Understand Concepts Strategy Practice As you master the concepts try explaining them to someone else. Reading Comprehension The Reading Comprehension segment consists of long passages. They can be upwards of 10 paragraphs or There are 3 passages each have 16 – 17 questions associated with it. more. The passages are frequently biology or technically based. And they require you to integrate your own knowledge with that being presented. 36/66 Page 19 DAT Biology Rapid Learning Series - Tutorial 01 © Rapid Learning Inc. All rights reserved. :: http://www.RapidLearningCenter.com 19 Multiple Choice Questions Which of the following hormones are not produced by the pituitary gland? A. ACTH B. TSH C. T4 D. FSH E. MSH ∎ Multiple choice questions that relate to biology require detailed k l d 37/66 knowledge. ∎ There are five options for each question. ∎ In a situation like this, unless you know the answer immediately, it is often helpful to write out the names for as many of the abbreviations that you know. ∎ In this case T4 is also known as thyroxine which is produced in the thyroid gland not the pituitary. The DAT does not test every single biology concept. So only study the topics that the DAT actually Time Management Study & Focus DAT actually tests. Do not study all Focus core study hours on weak areas. 38/66 Do not study all areas concurrently. Track mastery using practice exams. Check to see that the areas you are focusing on are improving. Page 20 DAT Biology Rapid Learning Series - Tutorial 01 © Rapid Learning Inc. All rights reserved. :: http://www.RapidLearningCenter.com 20 Forward Planning Plan ahead and set a study schedule. Schedule a couple of hours every day to study. Do not put off your study. 39/66 Take short practice tests every day and schedule complete exams weekly. Some students incorrectly believe that if they study more as the test date approaches, they will remember more. Long Term Study Goals Build long-term memory by studying in set doses ahead of time results in greater memory and understanding of concepts. Studies show the more “passes” you make over information the more you will “own” it. 40/66 Repetition of concepts and information over time is the winning way to master the DAT. Page 21 DAT Biology Rapid Learning Series - Tutorial 01 © Rapid Learning Inc.

Platelets and damaged tissue make clotting factor thromboplastin which with calcium and Vit K activates prothrombin to thrombin. Thrombin converts fibrinogen into fibrin. Fibrin threads coat the damaged tissue and trap The fluid remaining after blood clotting is called serum. Connect Concepts blood cells forming a clot. How would you connect this seemingly long chain of information Start by serum. Platelets+exposed collagen thromboplastin Ca+ Vit K 42/66 information. Start by drawing a picture. prothrombin thrombin fibrinogen fibrin Traps blood cells, forms a clot Page 22 DAT Biology Rapid Learning Series - Tutorial 01 © Rapid Learning Inc. All rights reserved. :: http://www.RapidLearningCenter.com 22 How Does Concept Connection Help? A person has a genetic defect in blood clotting. Defects in which of the following is not a likely cause of this problem? A. thromboplastin B. vit K deficiency C. platelet plug D. fibrinogen E. Thrombin ∎ By connecting concepts you know that the platelet plug is not a itself a t i d t 43/66 protein product. ∎ The platelet plug is the sum of events involving platelets contacting exposed collagen. ∎ So even if you didn’t know this specifically you could figure it out by connecting the concept of clotting proteins. Seek Answers to Your Questions If something is confusing or unclear get your questions resolved. Make absolutely sure that you have points of confusion resolved as soon as you identify them. Don’t put it off thinking that somehow they will “self clarify”. 44/66 Though tedious, these unanswered questions will show up again and probably on your DAT. Page 23 DAT Biology Rapid Learning Series - Tutorial 01 © Rapid Learning Inc. All rights reserved. :: http://www.RapidLearningCenter.com 23 Partial Comprehension For example let’s say you didn’t really understand what genetic code is, but you still manage to successfully discuss protein Then a more complex problem rests on this concept such as: ‘What is meant by the term y p synthesis superficially e.g. ‘ In a majority of proteins, AUG acts as the initiator codon.’ ‘What is meant by the term wobbling?’. Because of the superficial understanding of the concept of genetic code you cannot extrapolate it to “wobble”. 45/66 By ‘mental skimming’ you will submarine yourself on the DAT. But you can master these concepts and perform well if you plan and practice the plan. Study Avenues Practice problems will help you become confident in your mastery of the material and your guide as to what you should study next. Grab a Biology textbook: Solve these in-chapter review questions and chapter test problems and check your solutions in the manual. 46/66 Search online: There are countless practice problems to work out online. Grab a piece of paper and try to get the answer. Page 24 DAT Biology Rapid Learning Series - Tutorial 01 © Rapid Learning Inc.

Use the cheat sheets used in the Rapid Learning Tutorials. Cheat sheets are only useful as memory aids. You must master the Cheat sheets should include all key terms and concepts. Give yourself memory clues that work for you. Such as mnemonics, images or other memory games 47/66 detailed information in the Rapid Learning Modules to effectively utilize these. memory games. Flash Cards Flash Cards Other sources of flash cards Buy premade flash cards and focus only on those that you need practice with. Single small index cards with a question on one side and the answer on the other side Online web sites allow you to make your own custom flash cards and you can include images or other memory tricks. 48/66 Flash cards are not a replacement for detailed mastery of material. Use the information rich tutorials of Rapid Learning to get the necessary level of detail. Page 25 DAT Biology Rapid Learning Series - Tutorial 01 © Rapid Learning Inc.

Plan Your Attack the minute the test begins. Memorize the time format for the DAT before test day. Know Also know the types of questions in each segment. Test Format the instructions, time lines and order of the exam. 52/66 Page 27 DAT Biology Rapid Learning Series - Tutorial 01 © Rapid Learning Inc. All rights reserved. :: http://www.RapidLearningCenter.com 27 As Soon as You Start Pace yourself! At the start of each section, determine how much ti h d time you have and where you need to be at the end of the allotted time. Have your strategy before you start the test and run your If you have taken your ti thi 53/66 and run your strategy. practice exams, this should feel very familiar to you. You should use the same strategy in practice as you do on the test day. Time Limit per Question Set a time limit for each question, keep track on your watch. Don’t get “involved”. That is don’t become too interested in the science or you will science or you will loose track of time. 54/66 You can loose track of time by questions that are engrossing because of their difficulty or information content. Page 28 DAT Biology Rapid Learning Series - Tutorial 01 © Rapid Learning Inc. All rights reserved. :: http://www.RapidLearningCenter.com 28 “Focus” Minimize Distractions Focus builds confidence and will increase your speed, accuracy and score. Do not get distracted. Practice focus by building your test taking skills. 55/66 Write or make notes as needed. In the DAT, often two answers look similar. If you have answered the question in your mind before you read the solutions, you will not be confused by the options Think of the Answer! Read the question and before you begin scanning the answers come up with your own answer. confused by the options. The enzymes of Kreb’s cycle are located in: A. Cytoplasm B. Mitochondrial membrane 56/66 C. Mitochondrial matrix D. Microsomes E. Cell membrane For this question both Choice B or C , look similar. What does one do ?? Page 29 DAT Biology Rapid Learning Series - Tutorial 01 © Rapid Learning Inc. All rights reserved. :: http://www.RapidLearningCenter.com 29 Beware of the Familiar Beware of the Familiar: Test writers love to include something that seems very obvious as an answer choice. This tempts students to choose the wrong answer because it seems correct at first l Which of the following is true with regards to mitosis? A. Mitosis occurs in diploid cells only. B. Mitosis is a reductional division. C. Prophase I shows complex chromosomal behavior and five sub t glance. 57/66 stages. D. Mitosis consists of a single nuclear division. E. Mitosis can only occur in eukaryotes. In this problem, choice A is the trap because most students intuitively assume that mitosis occurs in diploid cells only. Beware of the Absolute The absolute answer is usually wrong because it only takes one exception to break the In most cases relative words like: possibly, sometimes often etc. indicate the correct answer. absolute. Answer A has already been disqualified. Notice that B is an “absolute” statement describing a process. Which of the following is true with regards to mitosis? 58/66 Beware the absolute statement such as “always”, “never”, “all” etc. A. Mitosis occurs in diploid cells only. B. Mitosis is a reductional division. C. Prophase I shows complex chromosomal behavior and five sub stages. D. Mitosis consists of a single nuclear division. E. Mitosis only occurs in eukaryotes. Page 30 DAT Biology Rapid Learning Series - Tutorial 01 © Rapid Learning Inc. All rights reserved. :: http://www.RapidLearningCenter.com 30 Answer Selection This leaves C and D as possible choices. E is one of those absolutes so may also be Which of the following is true with regards to mitosis? eliminated. D is correct. 59/66 A. Mitosis occurs in diploid cells only. B. Mitosis is a reductional division. C. Prophase I shows complex chromosomal behavior and five sub stages. D. Mitosis consists of a single nuclear division. E. Mitosis only occurs in eukaryotes. Dealing With Similar and Opposites Out of two opposite choices, one is usually correct. Similar choices are both incorrect. If two answer choices are very similar in wording, the answer is probably neither of them, because there can be only one correct answer. 60/66 However, if two answer choices are opposites, one of them is probably correct, because the test wants you to differentiate between the two core ideas. Page 31 DAT Biology Rapid Learning Series - Tutorial 01 © Rapid Learning Inc. All rights reserved. :: http://www.RapidLearningCenter.com 31 Choice A and B are opposites and should be the answers you focus on. The question implies there is a change so E is also eliminated. Significance of Opposites If you have no idea at all about which of these answers is correct, base your “guess” on the clue of it Induction is a process by which the synthesis of an enzyme in an organism is: A) Increased B) Decreased C) Controlled D) Inhibited opposites. 61/66 D) Inhibited E) No change In this case, the answer choice is A. By educated guessing, you may deduce that induction would be to increase something. Elimination and Answer Selection Choice B and choice C are opposite answers, Choice A and choice D, you should know, are automatically both incorrect, because they are the unrelated answers to the question. The best stimulant for secretion of insulin from beta cells in the islets of Langerhans in the pancreas is: pp out of which B is correct. E is wrong because it contradicts the statement within the question. 62/66 p A. Hyperlipidemic state B. Hyperglycemic state C. Hypoglycemic state D. Normoglycemic state E. Insulin is held constant not responsive to stimulation. Page 32 DAT Biology Rapid Learning Series - Tutorial 01 © Rapid Learning Inc.

B) End-product inhibiting the first enzyme in the sequence. C) Accumulation of intermediates in the sequence. D) End-products altering the kinetics of the sequence E) To much of the end product that is why it is called feed back. 63/66 For instance if you knew that the intermediates are not accumulated in the sequence. You can cross out answer choice C. You can cross out E because it seems not to address the question. Your odds of guessing the correct answer from 1-in-5 to 1- in-3.
