Question
Chapter 27.4, Problem 2QC
Summary Introduction
To review:
The structure that connects the conceptus (embryo) to the placenta.
Introduction:
During the fetal period, a temporary organ called the placenta is formed. It serves the major function of providing the fetus with nutrients and oxygen, and transferring waste from the fetus to the mother. This organ degenerates after the birth of the baby.

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.
