Question

5. If a bacterium using aerobic respiration was to degrade one lipid molecule that is composed of a glycerol molecule, a 12 carbon fatty acid an 18 carbon fatty acid, how many ATP would that cell make? Use the information below to build up your total number of ATP molecules. Assume no other carbon source is available. A. Glycerol is broken down to glyceraldehyde 3-phosphate, a glycolysis intermediate via the following pathway. Notice this process costs ATP but generates an FADH2. glycerol -> glycerol-3-phosphate -> dihydroxy-acetone-phosphate -> glyceraldehyde 3-phosphate ATP ADP FAD FADH2 B. Each fatty acid is broken down through a pathway which converts every two carbons into 1 acetyl-CoA.
