What is removed from pyruvate during its conversion into an acetyl group?
oxygen
atp
b vitamin
carbon dioxide

carbon dioxide

Explanation:

At end of glycolysis, two pyruvate molecules are formed which contain lots of energy that can be extracted by further processes.

Oxidation of pyruvate converts pyruvate which is a molecule with three carbons into acetyl CoA which is a two-carbon molecule which is attached to Coenzyme with the production of NADH  and one carbon dioxide molecule is released in the oxidation process.  

Acetyl CoA further acts as a fuel for citric acid cycle in next stage of cellular respiration.

Pyruvate + Coenzyme A + NAD⁺ ⇒ acetyl CoA + CO₂ + NADH + H⁺
