Question
Chapter 4.3, Problem 10AYP
Summary Introduction
To name:
A substance in the envelope structure of some bacteria that can cause severe symptoms in humans.
Concept introduction
Bacterial envelope includes cell wall, plasma membrane, and glycocalyx. The plasma membrane is composed of a phospholipid bilayer with the function of regulation of exit and entry of substances in and out of the cytoplasm. The cell wall contains mainly peptidoglycan and maintains the shape of the cell. Glycocalyx is a phospholipid layer that lies outside the cell wall and helps the bacteria to resist the immune reactions in the host body.

- 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.
