Detailed explanation-1: -Glycolysis is the first step of cellular respiration that breaksdown glucose into two molecules of pyruvic acid independent of presence or absence of oxygen.
Detailed explanation-2: -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-3: -Pyruvic acid, the simplest -ketoacid, plays a central role in sugar metabolism. It is the product of glycolysis, the anaerobic decomposition of glucose. In muscle, it is reduced to lactic acid during exertion. Pyruvic acid was featured in “Emergence” on PBS’s Nova program in 2007.
