- Does any step of the citric acid cycle directly produce ATP? Explain.arrow_forwardThe citric acid cycle is frequently described as the major pathway of aerobic catabolism, which means that it is an oxygen-dependent degradative process. However, none of the reactions of the cycle directly involve oxygen as a reactant.
