Question
Chapter 4, Problem 3S
Summary Introduction
To determine:
Whether the flagella are an example of a homologous or analogous trait considering the structure and function of the flagella found on eukaryotic and prokaryotic cells.
Introduction:
In terms of evolution, the homologous traits are derived traits are similar in structure as they are evolved from and the analogous traits are similar in function. Analogous trait is an example of the convergent evolution and homologous traits are inherited from the common ancestor.

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.
