A 70-kg adult person could meet all of his/her entire energy needs for one day by consuming 3 moles of glucose (540 g)- not a highly recommended diet!. Each molecule of glucose generates 30 ATP molecules when completely oxidized to CO2. The intracellular concentration of ATP is maintained in the cells at about 2 mM, and a 70-kg adult has about 25 liters of intracellular fluid. How many times per day, on average, does an ATP molecule turnover (= hydrolyzed and resynthesized)?
