Title: AP Biology 2018 Free-Response Questions Author: ETS Subject: Free-Response Questions from the 2018 AP Biology Exam Created Date: 2/2/2018 1:58:23 PM 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). A. 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. Because the question specifies that oxygen is required, the process depicted must show aerobic respiration rather than glycolysis. Terms and Conditions AP Biology Exam. Partner Solutions COVID-19 Updates The ADP levels in the transgenic mice were found to be higher than those in the wild type.

Choice B is incorrect because the tube exposed to light only had the highest rate of photosynthesis (increasing percent transmittance). During photosynthesis, DPIP is reduced and becomes colorless, which results in an increase in light transmittance. (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. (C) is incorrect because the lac− cells contain all the RNA molecules and nucleotides necessary to transcribe and translate the lactose-fermenting enzymes, provided they have the proper genes (which they can get from extract C), so they would also appear blue. Still trying to learn the details of peptides & steroid hormones? FAQ. 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. 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). The reaction occurring in organelle B is cellular respiration, as indicated by the release of energy stored in the bonds of glucose. 1. AP Biology 2020-2021 Class Handouts. We hope your visit has been a productive one. In an experiment, a solution of chloroplasts containing DPIP was divided among 4 tubes. At 30°C, the enzymes have denatured due to excess heat and the substrates have more difficulty binding to the active site. All gametes are unicellular, ruling out (D).

In a respiration experiment, transgenic mice (those possessing a particular genetic mutation) were compared to wild type (normal) mice. B. -, AP Biology Free-Response Practice Questions, AP Biology Multiple Choice Practice Questions, The Origin of Life and Natural Selection Notes, Biodiversity, Behavior, and Ecology Notes. The cecum can become a vestigial structure in carnivores, since it is shorter in species B and C than in species A and D. B. 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. Data questions are a series of questions about a single data set (graphs, charts, experiment summary). Choose your answers to the questions and click 'Next' to see the next set of questions. CA Privacy Policy, © Copyright Kaplan, Inc. All Rights Reserved. C: The pharmacist’s dilution of albumin was correct: when a solution of 25% albumin is diluted to contain five times as much water, it will have one-fifth of the original concentration, or 5% albumin. At 30°C, the substrate molecules have less kinetic energy than at 37°C. 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). How is the reaction between enzyme and substrate modified by the different temperatures? The AP Test Development Committees are responsible for developing each AP Exam, ensuring the exam questions are aligned to the course framework. This allows the reaction to proceed more rapidly.

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. The form of energy released in aerobic respiration is chemical energy in the form of ATP (E IV). AP Biology: Cell Biology Chapter Exam Instructions. If the transformation depicted in organelle B requires oxygen, what form of energy is represented by E IV? 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).
