Carbon dioxide

Answer 4

Pyruvic acid gets converted into acetyl coA, by losing a molecule of CO2, with the reduction of NAD to NADH2.

Then this acetyl coA combines with oxaloacetic acid, and gets converted into Citric acid.

hence, it is the "acetyl coA " that enters the krebs cycle.

the answer is thus: CO2.
