Work for Kaplan These online resources include all the information you need to succeed in this challenging advanced placement … -, The Origin of Life and Natural Selection Notes, Biodiversity, Behavior, and Ecology Notes. Press & Media A: A certain amount of energy (the activation energy) is needed for the reaction to take place. At 30°C, the substrate molecules have more kinetic energy than at 37°C. If you need to contact the Course-Notes.Org web … Dichlorophenolindophenol (DPIP), an electron acceptor that changes from blue to clear when reduced, can be used to visually determine the rate of photosynthesis. (D) is incorrect because the solution is hypo- tonic to the red blood cells, not hypertonic. This test contains 12 AP biology practice questions with detailed explanations, to be completed in 15 minutes.

The reaction occurring in organelle A is photosynthesis, as indicated by the splitting of water and fixation of CO. . Of the statements listed, the only one that logically follows is (A): in carnivores, the cecum becomes unnecessary, and starts to shorten. According to the data, an increase in light transmittance over time is found for the tube exposed to light only. Section I contains 120 multiple choice questions. This reduces the rate of random collisions and therefore the rate of the reaction. B. light reactions produce NADPH and ATP, while the Calvin cycle produces sugar. Quiz over photosynthesis that focuses on how oxygen is split, providing and electron that eventually results in the formation of ATP. Unit: Chemistry of life. Embryonic development, (A), does not reveal either of these characteristics, nor does fertilization, (C). What form of energy is represented by E II? Helpful Links. The cecum is a portion of the large intestine located near the junction of the small intestine and the large intestine. A. Choice B is incorrect because ADP levels would be greater when ATP is utilized (ATP → ADP + Pi). (C) The data on cecum length and diet are insufficient to draw conclusions about the relatedness of species, so rule out (C) and (D). Using the AP Biology Crash Course to Prepare for Success Beginning with the May 2013 test administration, the AP Biology exam is undergoing a radical change. At 30°C, the substrate molecules have less kinetic energy than at 37°C. C: DPIP acts as a substitute for NADP+ in photosynthesis. C. light reactions photophosphorylate ADP, while the Calvin cycle produces ATP. However, this practice test also has other information that makes it more helpful. Because those cells would be unable to ferment lactose, they would appear as colorless. A. 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). Based on the following information, which of the following conclusions is most plausible? 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. Researchers studied the activity of mevalonate kinase, an enzyme that may be important for biofuel production. The AP Test Development Committees are responsible for developing each AP Exam, ensuring the exam questions are aligned to the course framework.

After treatment with enzymes, each extract is incubated with live lac− cells and grown on a medium containing an indicator. Choice B is incorrect because the tube exposed to light only had the highest rate of photosynthesis (increasing percent transmittance). Please note that these external links are set to match the chapter format in Campbell & Reece Biology - AP … Learn vocabulary, terms, and more with flashcards, games, and other study tools. Nucleic acids. 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. 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). During photosynthesis, DPIP is reduced and becomes colorless, which results in an increase in light transmittance. STUDY GUIDE/ Chapter Summaries. These questions usually look for a cause-and-effect relationship, and are testable. It clearly lays out the course content and describes the exam and AP Program in general. ap_biology_cell_communication_unit_test_pracitce_frq.docx: File Size: 254 kb: File Type: docx: Download File.

Study Flashcards On BIOLOGY CHAPTER 14 PRACTICE QUESTIONS at Cram.com. The form of energy released in aerobic respiration is chemical energy in the form of ATP (E IV). Thus, (A) correctly characterizes this relationship. 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). Choice A is incorrect because DPIP changes from blue to clear when reduced during photosynthesis. The graph below shows the rate of a reaction as the concentration of ATP is increased while substrate concentration remains constant.

Extracts from lac+ cells are incubated separately with three different enzymes: extract A with protease K (which digests proteins), extract B with DNases (which digests DNA), and extract C with RNase H (which digests RNA). Terms and Conditions Higher transmittance is correlated to lighter color. Because the question specifies that oxygen is required, the process depicted must show aerobic respiration rather than glycolysis. AP Biology Multiple Choice Practice Questions April 6, 2020 / in AP Biology / by erinnelson 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.

In a respiration experiment, transgenic mice (those possessing a particular genetic mutation) were compared to wild type (normal) mice. C. Photosynthesis is stimulated when chloroplasts are exposed to light only. Look over the strategies for stand alone and data questions and then put the strategies to work with the following practice questions. Cell structure and function. Questions on the AP Biology exam will frequently ask students to analyze the results of a given experimental setup. The dilution was incorrect, resulting in a deficient concentration of albumin that led to the bursting of the red blood cells. Chemical energy being stored as glycogen. This is divided into three divisions which include: regular multiple choice questions, matching questions, and questions dealing with experiments for data. The onset of photosynthesis is visible when DPIP is oxidized and changes from clear to blue. The samples were then exposed to light (1500 lumens) and/or heat (85oC), and light transmittance was measured over time using a spectrophotometer. Free-Response Questions Download free-response questions from past exams along with scoring guidelines, sample responses from exam takers, and scoring distributions. COVID-19 Updates Data questions are a series of questions about a single data set (graphs, charts, experiment summary). B: Because the lac− cells contain everything necessary to construct enzymes that can ferment lactose except for the DNA with the lac+ genes, the only cells that would be adversely affected would be those incubated with extract B, which loses those genes due to the action of the DNases. Official practice tests provide the best preparation for the AP test. AP Biology Practice Exams Free Response Notes Videos Study Guides Click any of the links above for the best AP Biology practice exams, free response questions, notes, videos, and study guides.

If the transformation depicted in organelle B requires oxygen, what form of energy is represented by E IV? 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. B. comparing the diploid and haploid forms of the organism. 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. Contacts. Biology (Mader) 10th Edition In an emergency, a doctor can replace a patient’s blood plasma with a solution of 5% human albumin and 0.9% NaCl.
