What Happens to the Acetyl Groups Produced During Beta-Oxidation of Fat

Question

What happens to the acetyl groups produced during beta-oxidation of fat?
A)They directly enter the electron transport chain.
B)They directly enter the energy-yielding stages of glycolysis.
C)They are decarboxylated by pyruvate dehydrogenase.
D)They directly enter the citric acid cycle.
E)They are broken down in the cytoplasm.

Accepted Answer

The acetyl groups produced during beta-oxidation of fat are directly fed into the citric acid cycle, where they are oxidized to produce ATP through oxidative phosphorylation. This is the main way that the body generates energy from fat metabolism.
