Question
Chapter 23, Problem 15WIO
Summary Introduction
To determine:
The nonbiological analogies for Casparian strip and for pressure flow theory.
Concept introduction:
Casparian strip is a band of suberin and lignin substances deposited in the wall of endodermis. It is chemically distinct from the cell wall.
Pressure flow theory explains the mechanism of phloem transport from source to sink.

9. 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.

A. 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.
