Chapter 27, Problem 3CQ
Summary Introduction
To determine: The organisms that are responsible for forming blue-green blooms in warm weather on lake surfaces.
Introduction: When microorganisms rapidly increase and accumulate over surfaces of fresh or marine water system, they often lead to the formation of blue-green blooms. Blooms generally possess excess concentrations of mineral nutrients.

- 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.
