New questions in Biology . See AEROBIC RESPIRATION, ANAEROBIC RESPIRATION. Which of the following processes takes place in the cytosol of a eukaryotic cell? Glycolysis: Glycolysis is a set of 10 enzyme-catalyzed reactions that break down glucose in the cell. Pyruvic acid is formed as an end product of glycolysis, a process that breaks down glucose (a six-carbon molecule) into two molecules of pyruvate (a three-carbon molecule) and simultaneously yields a small net gain of the universal energy storage molecule adenosine triphosphate (ATP), used to power cellular function. Pyruvic acid is the final product of glycolysis, which is the first stage of cellular respiration. 2 ATP and 2 NADH are generated during the process of glycolysis using the energy that was originally in one molecule of glucose. pyruvic acid synonyms, pyruvic acid pronunciation, pyruvic acid translation, English dictionary definition of pyruvic acid.
