Question
Chapter 5, Problem 27E.3RQ
Summary Introduction
To explain: How to interpret the result when a culture fails to undergo a color change even after the addition of solutions A and B in nitrate reduction test.
Introduction: Nitrate reduction test is performed to determine the capability of an organism to reduce nitrate to nitrite by using an enzyme called nitrate reductase. If the medium turns red after adding the nitrate reagents then it is said to be positive for nitrate reduction.

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_forward
