Question
Chapter 22, Problem 42CYU
Summary Introduction
To review:
The process which is more important in the food movement along the small intestine, among the peristalsis and segmentation.
Introduction:
Peristalsis and segmentation both plays an important role in the movement of food along the digestive tract. Peristalsis is described as radially symmetrical contraction and relaxation of the muscles that produces a peristaltic wave. This peristaltic wave propel the bolus (ball of food) in oesophagus and upper digestive tract including stomach. Whereas the process of segmentation is accompained by the contraction of circular smooth muscles in back and forth direction to break and mix the food for the further movement.

- 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.
