Verified step by step guidance

Understand the context of the problem: Pyruvate oxidation is a key step in cellular respiration, occurring in the mitochondria after glycolysis.

Identify the reactant: Pyruvate, which is produced from glucose during glycolysis, is the starting molecule for pyruvate oxidation.

Recognize the process: Pyruvate is converted into Acetyl-CoA, a crucial molecule that enters the citric acid cycle (Krebs cycle).

Consider the byproducts: During the conversion of pyruvate to Acetyl-CoA, carbon dioxide (CO2) is released, and NAD+ is reduced to NADH.

Conclude with the main product: The main product of pyruvate oxidation is Acetyl-CoA, which is essential for the continuation of cellular respiration in the citric acid cycle.
