Complete β -oxidation of a 12-carbon fatty acid produces ____ molecules of FADH₂.

Question

Quizplus · Accepted Answer

Beta-oxidation of a fatty acid involves the cleavage of two carbon units (in the form of acetyl-CoA) from the carboxyl end of the fatty acid. Each cycle of beta-oxidation shortens the fatty acid by two carbons, produces one FADH2, one NADH, and one acetyl-CoA (except for the last cycle which produces two acetyl-CoA). For a 12-carbon fatty acid, there will be 5 cycles of beta-oxidation, producing 5 FADH2 molecules.
