Catabolism of fatty acids produces two-carbon molecules that are converted to acetyl CoA. The acetyl CoA molecules will most likely be metabolized in aerobic cellular respiration by which of the following mechanisms?
A) directly entering the electron transport chain
B) directly entering the energy-yielding phase of glycolysis
C) being converted to pyruvate and then undergo pyruvate oxidation upon transport into mitochondria
D) directly entering the citric acid cycle
