What stage of respiration immediately follows the process depicted below? two pyruvate molecules undergo a chemical reaction, combining with coenzyme a to form two acetyl-coa molecules. two carbon dioxide molecules and two nadh molecules are formed as a result of this process.

Kreb's cycle

Explanation:

Glycolysis is the first step of cellular respiration and breaks down glucose into two molecules of pyruvate. Link reaction includes the reaction of two molecules of pyruvate and CoA to form two molecules of acetyl CoA. The acetyl CoA enters Kreb's cycle and leads to the formation of CO2 and H2O. The redox reactions of Kreb's cycle use NAD+ and FAD+ as electron acceptors and reduce them into NADH and FADH2 respectively.
