Which statements describing $\beta$-oxidation of fatty acid are true? I. More energy is released in the oxidation of fatty acids than sugars. II. Only NAD⁺ / NADH are involved in the reactions. III. The series of four reactions is repeated until the entire fatty acid chain is degraded to acetyl- CoA) IV. The activated fatty acid is a carboxylic-diphosphoric mixed anhydride.

Question

Quizplus · Accepted Answer

I. Fatty acids release more energy upon oxidation than sugars due to their higher carbon to oxygen ratio, which allows for more energy-rich electron pairs to be transferred to the electron transport chain. III. The β-oxidation cycle repeats, shortening the fatty acid chain by two carbon atoms (as acetyl-CoA) each time, until the entire chain is converted into acetyl-CoA units.
