The answer is Pyruvate.

Because the action of Pyruvate dehydrogenase takes place in the mitochondrial matrix though we know that the inner membrane of mitochondrial is impermeable but the mitochondrial matrix is the part of the mitochondrion.

Under aerobic conditions pyruvate is transported to mitochondrial matrix where it is oxidatively decarboxylated by pyruvate dehydrogenase to form acetyl Co-A.

Ans: Pyruvate.

The compound that enters Mitochondria during Aerobic respiration is acetyl CoA. Pyruvate converted to Acetyl CoA which leads to Krebs cycle.

Yes, @Ahmad.

The correct answer is acetyl CoA.

David yerima said:   9 years ago
Yes I agree with Ahmad because pyruvate most undergoes preparatory stage i.e pyruvate oxidation before it can't pass through the mitochondrial membrane.

The compound that enters is pyruvate because the intermediate reaction of aerobic respiration which involves the pyruvate dehydrogenase complex takes place in the mitochondria. Since pyruvate dehydrogenase is mitochondrial, thus the conversion of pyruvate to acetyl coa takes place in the mitochondria.

Ahmad Anas M said:   1 decade ago
The compound that enters Mitochondria during Aerobic respiration is not pyruvate. The correct answer is acetyl CoA. Pyruvate most be converted to Acetyl CoA which leads to Krebs cycle.
