9. 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 9 glycerol A. 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 dihydroxy- acetone- phosphate Glyceraldehyde- 3-phosphate ATP ADP FAD FADH2 B. Each fatty acid tail of the lipid is broken down through a pathway called Beta-oxidation which converts every two carbons of a fatty acid into 1 acetyl-CoA. First, using the total number of carbons in each fatty acid, determine how many acetyl-CoA you will produce. Then using the total number of acetyl-CoA determine how many ATP will be produced using aerobic respiration. 12+18 = 30 ÷ 2 = 15 acetyl-CoA NADH FADH2 OP ATP SLP ATP Total ATP Glycerol 5 2 2 molecules Fatty acids 45 NADH 15 FADH2 145 ATP 15 Total Show your work on the following page... 5
