Chapter 21, Problem 1A
Summary Introduction
To review:
The explanation of a physician advising the family on condition of diphtheria patient that why the disease affects some tissues but not others.
Introduction:
Diphtheria is a toxin-mediated deadly disease caused by Corynebacterium diptheriae. It is non-spore forming, Gram-positive, rod-shaped, pleomorphic bacteria. The infection of diphtheria starts with a constant sore throat, fever with extreme fatigue. After some days of infections neck of patients swells.

- 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.
