Question
Chapter 25, Problem 10RQ
Summary Introduction
To review:
The difference between exotoxins and endotoxins.
Introduction:
Microbes are the smallest organisms that are also termed as microorganisms as they are microscopic in nature. Some microbes are harmful in nature while the rest are friendly and present everywhere such as in the soil, air, and water. Microbes after attaching to the host cells will secrete protein toxins called exotoxin that will kill the cell and unlock its nutrients to be utilized by the microbes.

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_forward
