Textbook Question
Chapter 3, Problem 28E
As you know, fatty acids can be oxidized to provide energy for making ATP. This process begins with a set of reactions known as the fatty acid oxidation cycle, or beta oxidation. Before entering the cycle, a fatty acid reacts with coenzyme A to form a molecule called fatty acyl CoA. This molecule then enters the cycle and continues to go through it until all its carbons have been eliminated, as shown on the following page. From your examination of this diagram, answer the following questions for a 1 2-carbon fatty acid.
- How many acetyl CoA molecules will be produced by beta oxidation of this fatty acid? How many ATP molecules can be produced from each acetyl CoA molecule that goes through the Krebs cycle and oxidative phosphorylation?
- How many NAD+ and FAD molecules will be reduced? (Hint: How many bonds must be broken to split a 12-carbon fatty acid into acetyl CoA molecules?)
- How many ATP molecules will be produced per each NADH + H+ and each FADH2 molecule that provides electrons to the electron transport system?
- It takes two ATP molecules to get the cycle started. Based on this information and your answers to the previous questions, how many ATP molecules can be generated from a 1 2-carbon fatty acid?

- Use the following information to answer the question(s) below. Martin Wikelski and L. Michael Romero (Body size, performance and fitness in Galápagos marine iguanas, Integrative and Comparative Biology 43 [2003]:376-86) measured the snout-to-vent (anus) length of Galápagos marine iguanas and observed the percent survival of different-sized animals, all of the same age. The graph shows the log snout-vent length (SVL, a measure of overall body size) plotted against the percent survival of these different size classes for males and females. Survival (%) 100- 80- 60- 40- 20- 0+ 1.9 T 2 2.1 2.2 2.3 2.4 2.5 2.6 2.7 Log SVL (mm) 19) Examine the figure above. What type of selection for body size appears to be occurring in these marine iguanas? A) directional selection B) stabilizing selection C) disruptive selection D) You cannot determine the type of selection from the above information. 3arrow_forward24) Use the following information to answer the question below. Researchers studying a small milkweed population note that some plants produce a toxin and other plants do not. They identify the gene responsible for toxin production. The dominant allele (T) codes for an enzyme that makes the toxin, and the recessive allele (t) codes for a nonfunctional enzyme that cannot produce the toxin. Heterozygotes produce an intermediate amount of toxin. The genotypes of all individuals in the population are determined (see table) and used to determine the actual allele frequencies in the population. TT 0.49 Tt 0.42 tt 0.09 Refer to the table above. Is this population in Hardy-Weinberg equilibrium? A) Yes. C) No; there are more homozygotes than expected. B) No; there are more heterozygotes than expected. D) It is impossible to tell.arrow_forward30) A B CDEFG Refer to the accompanying figure. Which of the following forms a monophyletic group?

- Molecular Biology Question. Please help with step solution and explanation. Thank you: The Polymerase Chain Reaction (PCR) reaction consists of three steps denaturation, hybridization, and elongation. Please describe what occurs in the annealing step of the PCR reaction. (I think annealing step is hybridization). What are the other two steps of PCR, and what are their functions? Next, suppose the Tm for the two primers being used are 54C for Primer A and 67C for Primer B. Regarding annealing step temperature, I have the following choices for the temperature used during the annealing step:(a) 43C (b) 49C (c) 62C (d) 73C Which temperature/temperatures should I choose? What is the corresponding correct explanation, and why would I not use the other temperatures?
