The oxidation of glucose to CO2 and H2O with the subsequent production of energy is best reflected in which of the following statements?

A. Glucose is oxidized in a stepwise fashion beginning with the Enbden-Meyerhof pathway and continuing with the TCA cycle where the remainder of the energy from the glucose is harnessed in oxidized coenzymes, which transport electrons to an electron transport chain where ATP is made by substrate-level phosphorylation. B. Glucose is reduced in a stepwise fashion beginning with the TCA cycle and continuing with a glycolytic pathway where the remainder of the energy from the glucose is harnessed in oxidized coenzymes, which transport electrons to an electron transport chain where ATP is made by oxidative phosphorylation. C. Glucose is reduced in a stepwise fashion beginning with the Entner-Doudoroff pathway and continuing with the TCA cycle where 38 molecules of ATP are made by oxidative phosphorylation. D. Glucose is oxidized in a stepwise fashion beginning with a glycolytic pathway and continuing with the TCA cycle where the remainder of the energy from the glucose is harnessed in reduced coenzymes, which transport electrons to an electron transport chain where ATP is made by oxidative phosphorylation.
