The majority of fatty acids get converted to Acetyl CoA. Is it possible to use fatty acids as a continual source of energy in the absence of oxygen?

a. No, because Acetyl CoA goes into the TCA cycle, which will not occur in cells without oxygen.

b. Yes, because cells can use the Acetyl CoA in the principal reactions of glycolysis in the cytosol

c. No, because cells cannot make any energy in the absence of oxygen

d. Yes, because Acetyl CoA gets converted into molecules of ATP and this does not need oxygen.

    a. No, because Acetyl CoA goes into the TCA cycle, which will not occur in cells without oxygen.

    Explanation:

    Fatty acids in the body gets converted to acetyl-CoA by the process of β-oxidation. After the conversion of fatty acids to acetyl-CoA, acetyl-CoA undergoes the TCA cycle which produces NADH and FADH₂ which further undergoes electron transport chain where oxygen gas acts as the final receptor for these molecules and high energy molecules known as ATP are released in the process.

    Thus, in the absence of oxygen, TCA will not occur and thus no energy is provided to the body.
