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.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.
After four generations, the following results were obtained.
Unit 8 (Chemical Evolution, Prokaryotes, Eukaryote Evolution, Protista) 36.
Explain how ATP is involved in each example you choose.
Unit 5 (Meiosis, Mendelian Genetics, DNA Replication) 17.
A portion of specific DNA molecule consists of the following sequence of nucleotide triplets.
TAC GAA CTT GGG TCC This DNA sequence codes for the following short polypeptide.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.Labeled diagrams that are explained in your answer may be useful.Unit 6 (Protein Synthesis, Gene Expression, DNA Technology) 21.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?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.Include in your answer (a) a description of how you would set up and perform the experiment: (b) the results you would expect from your experiments: and (c) an explanation of those results based on the principles involved.(Be sure to clearly state the principles addressed in your discussion.) 9. Choose THREE of the following four types of cellular transport.
