Detailed explanation-1: -The final products are two molecules of pyruvate and ATP.
Detailed explanation-2: -Two molecules of pyruvate are converted into two molecules of acetyl CoAstart text, C, o, A, end text. Two carbons are released as carbon dioxide-out of the six originally present in glucose.
Detailed explanation-3: -In eukaryotic cells, the pyruvate molecules produced at the end of glycolysis are transported into mitochondria, which are the sites of cellular respiration. There, pyruvate will be transformed into an acetyl group that will be picked up and activated by a carrier compound called coenzyme A (CoA).
Detailed explanation-4: -Recall that glycolysis, stage I of cellular respiration, produces two molecules of pyruvate. These molecules enter the matrix of a mitochondrion, where they start the Krebs cycle. The reactions that occur next are shown in Figure below.
