Quizplus · Accepted Answer

Acetyl-CoA formation (also known as pyruvate oxidation) produces NADH and CO₂, and involves the conversion of pyruvate to acetyl-CoA by the enzyme pyruvate dehydrogenase. This occurs in the mitochondrial matrix, and is a crucial step in the aerobic respiration of glucose.

(Note: option B refers to the overall process of cellular respiration, not specifically to acetyl-CoA formation.)
