Question
Chapter 23, Problem 20CP
Summary Introduction
To review:
The alveolar ventilation rate and forced expiratory volume in 1 second.
Introduction:
During respiration, the air flows from atmosphere into the lungs and out from the lungs into the atmosphere. However, the amount of air entering and leaving depends on different factors such as lung volumes and lung capacity.

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.
