Fatty acids usually have an even number of carbons in their structures.They are catabolized by a process called beta-oxidation.The end products of the metabolic pathway are acetyl groups of acetyl CoA molecules.What is the most likely fate of the acetyl groups?
A)They directly enter the electron transport chain.
B)They directly enter the energy-yielding stages of glycolysis.
C)They are directly decarboxylated by pyruvate dehydrogenase.
D)They directly enter the Krebs cycle.
