Chapter 51.1, Problem 3EQ
Summary Introduction
To determine: The proposed evolutionary benefit of sexual reproduction.
Introduction: The two different modes of reproduction are sexual reproduction and asexual reproduction. Asexual reproduction involves the production of offspring with genes inherited from a single parent. The offspring is genotypically similar to the parent organism. Sexual reproduction involves the fusion of two haploid gametes to form a diploid zygote. Both the haploid gametes are from two different parents and the offspring is not an exact copy of any one parent.

- Aerobic respiration of one lipid molecule. The lipid is composed of one glycerol molecule connected to two fatty acid tails. One fatty acid is 12 carbons long and the other fatty acid is 18 carbons long in the figure below. Use the information below to determine how much ATP will be produced from the glycerol part of the lipid. Then, in part B, determine how much ATP is produced from the 2 fatty acids of the lipid. Finally put the NADH and ATP yields together from the glycerol and fatty acids (part A and B) to determine your total number of ATP produced per lipid. Assume no other carbon source is available. 18 carbons fatty acids 12 carbons glycerol . Glycerol is broken down to glyceraldehyde 3-phosphate, a glycolysis intermediate via the following pathway shown in the figure below. Notice this process costs one ATP but generates one FADH2.
