Chapter 50.4, Problem 1CS
Summary Introduction
To propose: A revised model to depict the effect on Ca2+ homeostasis if bone cells are unable to respond to PTH (parathyroid hormone).
Introduction: Skin cells in the mammals that are receiving regular exposure to sunlight produces vitamin D from the precursor 7-dehydrocholesterol. Blood Ca2+ concentration does not decrease due to the secretion of parathyroid hormone. Bone cells release extra Ca2+ from the bones thereby increasing the concentration of calcium in the blood.

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_forward
