Rate of ATP Turnover in Rat Heart Muscle Rat heart muscle operating aerobically fills more than 90% of its ATP needs by oxidative phosphorylation. Each gram of tissue con-sumes O2 at the rate of 10.0 mol/min, with glucose as the fuel source.(a) Calculate the rate at which the heart muscle con-sumes glucose and produces ATP.(b) For a steady-state concentration of ATP of 5.0 mol/g of heart muscle tissue, calculate the time required (in sec-onds) to completely turn over the cellular pool of ATP. What does this result indicate about the need for tight regulation of ATP production
