Chapter 42.1, Problem 1TC
Summary Introduction
To determine:
The reason why natural selection favor aphids that alternate between asexual and sexual reproduction at different seasons of the year.
Introduction:
Aphids are the tiny sap-sucking insects belong to the superfamily Aphidoidea. These are distributed worldwide, but are commonly found in the temperate region. They have soft bodies which may be black, green, pink and brown in color. They can be alternate between asexual and sexual mode of reproduction within the same host at different seasons of the year.

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. Continue generating ATP with glyceraldehyde-3-phosphate using the standard pathway and aerobic respiration. glycerol glycerol-3- phosphate…arrow_forwardDon't copy the other answerarrow_forward
