Sugars are used by many chemoheterotrophs as an important source of carbon and energy. Indeed, complete oxidation of glucose using oxygen as a terminal electron acceptor has a free energy change of -2,883.0 kJ/mol. What strategy do cells use to minimize the amount of that energy that is lost as heat during the catabolism of sugars? Choose one: A Energy is harvested using a series of smaller oxidations B. Oxidations of sugars directly power membrane-bound ATP synthases. C. The cells...
