Higher than normal levels of ADP suggest that the transgenic mice are unable to convert ADP to ATP as efficiently because the mutation has impaired their mitochondria. The form of energy released in aerobic respiration is chemical energy in the form of ATP (E IV). (D) is incorrect because the solution is hypo- tonic to the red blood cells, not hypertonic. Quickly memorize the terms, phrases and much more. 1. What form of energy is represented by E II?

Organisms that reproduce sexually exhibit zygotic, gametic, or sporic meiosis. The correct answer is (C). Answer the following questions about the various processes depicted in the diagram and about the cell in which they are occurring. The AP Biology exam is three hours long and is divided into two sections. (C) The data on cecum length and diet are insufficient to draw conclusions about the relatedness of species, so rule out (C) and (D). Practice. Life cycles are characterized by the timing of meiosis and the characteristics of the diploid and haploid generations. Thus, (A) correctly characterizes this relationship. Helpful Links. The multiple choice questions are composed of two types of questions, stand alone and data questions. Stand alone questions are your average multiple choice question and make up a little over half of the questions in the section.

CA Privacy Policy, Test Your Skills, Take a Practice AP Biology Quiz, A. light reactions produce sugar, while the Calvin cycle produces O, D. the Calvin cycle produces both sugar and O, The data here suggest that the cecum is four to five times longer in species that consume plant matter for their diets (A and D) compared to those that consume at least some meat (B and C). In the multiple choice section of the AP Biology test, you will have 90 minutes to answer 60 multiple choice questions and 6 grid-in items. The dilution was incorrect, resulting in a deficient concentration of albumin that led to the bursting of the red blood cells. Cell structures and their functions: Cell structure and function Cell size: … In an experiment, a solution of chloroplasts containing DPIP was divided among 4 tubes. FAQ. Light reactions, which convert solar energy into chemical energy (ATP, NADPH) in the thylakoid membranes, fuel the Calvin cycle’s production of sugars in the stroma. Choice B is incorrect because ADP levels would be greater when ATP is utilized (ATP → ADP + Pi). Choice D is incorrect because the solution in all four tubes was blue at time 0. AP Biology Practice Test 41. Free-Response Questions Download free-response questions from past exams along with scoring guidelines, sample responses from exam takers, and scoring distributions. Of the statements listed, the only one that logically follows is (A): in carnivores, the cecum becomes unnecessary, and starts to shorten. These questions usually look for a cause-and-effect relationship, and are testable. A: A certain amount of energy (the activation energy) is needed for the reaction to take place. Still trying to learn the details of peptides & steroid hormones? In an emergency, a doctor can replace a patient’s blood plasma with a solution of 5% human albumin and 0.9% NaCl. The cecum evolved to have an important role in the digestion of protein, since it is shorter in species B and C than in species A and D. C. Species A is more closely related to species D than to species B, because A and D are both herbivores. Embryonic development, (A), does not reveal either of these characteristics, nor does fertilization, (C). The AP Exam development process is a multiyear endeavor; all AP Exams undergo extensive review, revision, piloting, and analysis to ensure that questions are accurate, fair, The following table lists the diets of several vertebrates, as well as the average length of the cecum as measured in 20 individuals of that species.

This is divided into three divisions which include: regular multiple choice questions, matching questions, and questions dealing with experiments for data. D. the Calvin cycle produces both sugar and O2. At 30°C, the enzymes have denatured due to excess heat and the substrates have more difficulty binding to the active site. (B) is incorrect because there is more kinetic energy at higher temperatures, not at lower temperatures, and because increased kinetic energy actually raises the likelihood that the substrate will bind to the enzyme. A. D. The dilution of albumin in distilled water caused the shriveling of the red blood cells because the solution was hypertonic to the red blood cells. The first reaction in this organelle represents the light reactions, in which the sun’s energy is converted to chemical energy in the form of ATP (E II). Contact Us C. Photosynthesis is stimulated when chloroplasts are exposed to light only. You can be sure that the questions are accurate representations of what you'll see on the final exam.Unfortunately, I could only find one official practice test for the new version of the AP Biology test since the format and content changed so recently (2012). The reaction occurring in organelle B is cellular respiration, as indicated by the release of energy stored in the bonds of glucose. (B) is the opposite of what we expect; it would be logical if it played a prominent role in digesting. Credit will be awarded for scientific questions.

Each form of energy is represented by the symbols E I–E IV. Chapter 1 Keys for Success on the AP Biology Exam I. How can the consequence of the administration of substitute plasma be explained? In a respiration experiment, transgenic mice (those possessing a particular genetic mutation) were compared to wild type (normal) mice. The AP Test Development Committees are responsible for developing each AP Exam, ensuring the exam questions are aligned to the course framework. Choice A is incorrect because a higher rate of oxygen consumption in mitochondria would decrease ADP levels (electrons are transferred to oxygen when ADP is phosphorylated to make ATP). COVID-19 Updates AP Biology can lead to a wide range of careers and college majors. The graph below shows the rate of a reaction as the concentration of ATP is increased while substrate concentration remains constant. Choice D is incorrect because carbon dioxide is released, not consumed, in cellular respiration. Official practice tests provide the best preparation for the AP test. The rate of oxygen consumption in mitochondria was higher in transgenic mice. (C) is incorrect because 30°C is actually a higher temperature than 37°C, so it makes no sense to say that the protein “denatured due to excess heat.” (D) is incorrect because substrate concentration remains constant, according to the question stem. B. The AP Biology test is divided into two sections. Partner Solutions Every Student of STD-10 can practice the Biology Chapter-2 “Respiration” (Zoology & Botany) Subject completely with the objective type of Multiple Choice Questions for 25 Questions for a total of 25 Marks with a time duration of 25 minutes, and there is no limit to practice … Quiz over photosynthesis that focuses on how oxygen is split, providing and electron that eventually results in the formation of ATP. Dichlorophenolindophenol (DPIP), an electron acceptor that changes from blue to clear when reduced, can be used to visually determine the rate of photosynthesis. The data here suggest that the cecum is four to five times longer in species that consume plant matter for their diets (A and D) compared to those that consume at least some meat (B and C). C. determining when in the life cycle fertilization occurs. Because the resulting solution was hypotonic to the red blood cells, water from the solution osmosed into the cells, causing them to burst, as in (C).

All Rights Reserved. A. Two cellular organelles are represented by the letters A and B. (B) is thus correct. C: Aerobic phases of cellular respiration in eukaryotes occur in mitochondria, which synthesize ATP from ADP. At higher temperatures, there is more kinetic energy and the increased rate of random collisions between molecules increases the probability that they will collide in the right way to react.
