Question: what product of the krebs cycle is being exhaled by you right now?
Answer: Step 2: The transformation of pyruvate to acetyl CoA The carbon that is removed takes two oxygens from pyruvate with it, and exits the body as carbon dioxide (CO 2​start subscript, 2, end subscript). CO 2​start subscript, 2, end subscript is the waste product that you release when you exhale.
