Include in your discussion the major reactions, the end products, and energy transfers. The rate of photosynthesis may vary with changes that occur in environmental temperature, wavelength of light, and light intensity.Using a photosynthetic organism of your choice, choose only ONE of the three variables (temperature, wavelength of light, or light intensity) and for this variable 12.The following is a comprehensive list of essay questions that have been asked on past AP exams. Select three properties of water and: Unit 2 (Organic Chemistry, Biochemistry, and Metabolism) 2.
Describe each classical experiment and indicate how it provided evidence for the chemical nature of the gene. Discuss Mendel’s laws of segregation and independent assortment.
Explain how the events of meiosis I account for the observations that led Mendel to formulate these laws. An organism is heterozygous at two genetic loci on different chromosomes.
The arrows indicate reaction sites for two restriction enzymes (enzyme X and enzyme Y). Assume that a particular genetic condition in a mammalian species causes an inability to digest starch.
This disorder occurs with equal frequency in males and females. Include in your discussion the factors that may contribute to the maintenance of genetic isolation. Do the following with reference to the Hardy-Weinberg model. In a laboratory population of diploid, sexually reproducing organisms a certain trait is studied.
Describe the fluid-mosaic model of a plasma membrane. Include a description of mitosis and cytokinesis, and of the other phases of the cell cycle. After realizing the error, the assistant randomly labeled the flasks containing these four unknown solutions as flask A, flask B, flask C, and flask D.
Discuss the role of the membrane in the movement of materials through it by each of the following processes: 6. Indicate the ways in which a nonphotosynthetic prokaryotic cell would differ in structure from this generalized eukaryotic plant cell. Design an experiment, based on the principles of diffusion and osmosis, that the assistant could use to determine which of the flasks contains each of the four unknown solutions.Describe the light reactions of photosynthesis and, for both a C3 and a C4 plant, trace the path of a carbon dioxide molecule from the point at which it enters a plant to its incorporation into a glucose molecule.Include leaf anatomy and biochemical pathways in your discussion of each type of plant. Explain what occurs during the Krebs (citric acid) cycle and electron transport by describing the following: 15. For 3 of the following 5 processes involving energy transfer, explain how each functions in the cell and give an example.methionine – leucine – glutamic acid – proline – arginine Describe the steps in the synthesis of this polypeptide.What would be the effect of a deletion or an addition in one of the DNA nucleotides?Describe the chemical composition and configuration of enzymes and discuss the factors that modify enzyme structure and/or function. After an enzyme is mixed with its substrate, the amount of product formed is determined at 10-second intervals for 1 minute.Data from this experiment are shown below: Unit 3 (Cell Structure and Function, Cell division) 5. A laboratory assistant prepared solution of 0.8 M, 0.6 M, 0.4 M, and 0.2 M sucrose, but forgot to label them.You can download and preview AP Biology test questions and answers in text format or you can download in MS Word format.You may also be interested in traveling to the College Board and learning more about the AP Program and about AP Biology.Labeled diagrams that are explained in your answer may be useful.Unit 6 (Protein Synthesis, Gene Expression, DNA Technology) 21.
