Question
Chapter 28.4, Problem 3MC
Summary Introduction
To compare:
The hormones of the adrenal cortex and adrenal medulla.
Concept introduction:
The adrenal glands are pyramid-shaped organs on top of the kidney. The two segments are the inner adrenal medulla, which is more like more like nervous tissue than a gland, is a part of nervous system. The outer adrenal cortex, encapsulating the medullary region and forms the bulk of the gland.

- Aerobic respiration of one lipid molecule. 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_forward4.
