Verified step by step guidance

Understand the context of pyruvate oxidation: Pyruvate oxidation is a crucial step in cellular respiration that links glycolysis to the citric acid cycle.

Identify the location of pyruvate oxidation: Pyruvate oxidation occurs in the mitochondria, not in the cytoplasm. This is a key point to remember.

Review the conversion process: Each pyruvate molecule is converted into an acetyl-CoA molecule, which is then used in the citric acid cycle.

Examine the role of NAD+: During pyruvate oxidation, NAD+ is reduced to NADH, which is an important electron carrier in cellular respiration.

Consider the by-products: Carbon dioxide is released as a by-product of pyruvate oxidation, which is a common feature of decarboxylation reactions in metabolism.
