Heart muscle gets most of the ATP needed to power its continual contractions through oxidative phosphory- lation. When oxidizing glucose to heart muscle con- sumes t a rate of per g of tissue, in order to replace the ATP used in contraction and give a steady- state ATP concentration of of tissue. At this rate, how many seconds would it take the heart to consume an amount of ATP equal to its steady-state levels? (Com- plete oxidation of one molecule of glucose to yields 30 ATP, 26 of which are derived by oxidative phosphoryla- tion using the 12 pairs of electrons captured in the electron carriers NADH and
