Vedclass · Answer

(A) The complete oxidation of carbohydrates occurs during aerobic respiration,which involves the Krebs cycle and the Electron Transport System $(ETS)$.In the Krebs cycle,the acetyl group of Acetyl $CoA$ is completely oxidized to $CO_2$ and $H_2O$,releasing a significant amount of energy in the form of $NADH$ and $FADH_2$.These electron carriers then donate electrons to the $ETS$,where the majority of $ATP$ is synthesized through oxidative phosphorylation.Therefore,the liberation of most of the energy occurs when pyruvic acid (after conversion to Acetyl $CoA$) is completely oxidized to $CO_2$ and $H_2O$.

Most of the energy in the cell is liberated by the oxidation of carbohydrates when:
