Question

In the presence of oxygen, cells oxidize glucose completely to carbon dioxide and water according to the chemical equation: C6H12O6 + 6O2 → 6CO2 + 6H2O. In the process, about 35 molecules of ATP are generated per molecule of glucose oxidized, so that some of the energy released by oxidation is recovered as usable chemical energy. The principal role of O2 in this process is to: a - React with glucose to cleave it into smaller fragments for further oxidation b - Participate as a reactant in the generation of ATP from ADP and Pi c - Supply the oxygen for CO2 production d - Accept electrons released by glucose oxidation, forming H2O
