All of the above are correctly matched.
Glycolysis is the process wherein glucose (from the diet) is broken down to two molecules of pyruvate through a 10-step enzymatic reaction. This reaction occurs in the cell's cytoplasm or cell body. Once pyruvate is formed, the pyruvate dehydrogenase complex, an enzyme complex responsible for converting pyruvate into acetyl-CoA.
Acetyl-CoA will then be transported to the mitochondria and it will cycle through series of reduction-oxidation reactions in the Kreb's cycle (also known as the tricarboxylic acid cycle or the citric acid cycle). Various reducing compounds (NADH and FADH2) are formed and these reducing compounds are oxidized, still, in the mitocondria in the electron transport chain producing ATP via oxidative phosphorylation.
