Answer to Question #184816 in Biochemistry for Emmers Occean

Question

Calculate the amount of ATP generated from the complete oxidation of a triglyceride with a X, Y, and Z acyl chain of carbons; include an accounting of the electron carriers and molecules of ATP produced at each stage of metabolism. Compare the ratio of ATP:C to that achieved by the complete oxidation of glucose muscle cells. Describe how the acetyl units would be used during [normal/low] [glucose] periods.

Answer 1

Triglyceride is broken down by hydrolysis into principal components, fatty acids and glycerol. The fatty acids are then oxidized into acetyl CoA for energy production. Triglyceride contain three fatty acid molecules in which form 441ATP molecules (38*147) and 19 ATP molecules form during glycerol breakdown generating a total of 460 molecules of ATP for each triglyceride molecule catabolized. Complete oxidation of glucose produces 38 ATP, 2 from glycolysis, 2 from Krebs cycle and about 34 from electron transport system. Acetyl units are delivered to the citric acid cycle by acetyl enzyme to be oxidized for energy production
