Aerobic respiration to the pyruvic acid molecules

Question

What occurs throughout aerobic respiration to the pyruvic acid molecules made up by glycolysis? What is the series of reactions which then follows?

Answer 1

The pyruvic acid molecules made up in cytosol through glycolysis enter into the mitochondria.

In the mitochondria each and every pyruvic acid molecule is transformed into one molecule of acetyl-CoA (that is, acetyl coenzyme A) with release of one carbon-dioxide. The Krebs cycle (also termed as citric acid cycle), the second phase of aerobic respiration, then starts.
