Question
Chapter 24, Problem 15PIAT
Summary Introduction
To review:
If the use of DNA (deoxyribonucleic acid) of humans for the purpose of phylogenetic relationship to determine the occurrence of mating is legitimate or not.
Introduction:
Humans have always been curious to know about their origin. The study of the human DNA and comparing it to the DNA of the primitive individuals of the human species is one of the most concrete ways to find the evolutionary link.

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
