Solution

Conversion of pyruvate acetyl CoA in presence of oxygen:

  1. Pyruvate is the end product of glycolysis.
  2. Pyruvate is a three-carbon molecule that enters the mitochondria for aerobic respiration,
  3. In presence of plenty of oxygen, aerobic respiration starts with the conversion of 3 carbon molecule to 2 carbon molecule i.e. acetyl CoA.
  4. This conversion takes place in three steps they are decarboxylation, the reduction of NAD+, and the attachment of coenzyme A.
  5. After the decarboxylation process, acetyl CoA enters the citric acid cycle.
