Which of the following statements correctly and most accurately describes the function of FAD in the pyruvate dehydrogenase enzyme complex? A)NADH passes electrons to FAD to form FADH₂. B)Lipoamide passes electrons through FADH2,which almost instantly passes them to NAD thus forming NADH. C)FADH₂ donates electrons to lipoamide thus regenerating FAD. D)Lipoamide oxidizes NADH to NAD by passing electrons to FAD. E)NAD accepts electrons directly from lipoamide,which has gained them via oxidation of FADH₂.

Lipoamide passes electrons to FAD within the pyruvate dehydrogenase complex, which then almost instantly passes them to NAD+, forming NADH. This process is part of the mechanism by which the complex facilitates the conversion of pyruvate into acetyl-CoA, with FAD acting as an intermediate electron carrier.
