Acetyl CoA is the substance generated just after glycolysis in preparation for Krebs cycle. In creating acetyl coA, pyruvate (the product of glycolysis) enters the mitochondrion via active transport, and is oxidized through the reduction of NAD+ to NADH.

A. reduces FADH to FAD
B. drives the oxaloacetate to form citrate
C. creates a proton gradient
D. generates directly ATP
E. reduces oxygen to water
