Chapter 24, Problem 1CT
Summary Introduction
To describe: A situation where human could be a link in a food chain, but not to the top predator.
Introduction: Food chain represents the transfer of food energy from one trophic level to successive trophic levels. A food chain begins with the producers that synthesize food by the process of photosynthesis. The producers are eaten by herbivores which in turn are eaten by carnivores. The carnivores are then eaten by some other carnivores or get decomposed by micro-organisms after they die.

- 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.
