Ans.
Glycolysis is a biochemical process that involves breakdown of sugar molecules (usually glucose) into pyruvate and release of energy in the form of ATP. During this process , one molecule of glucose makes two molecules of pyruvate, two molecules of ATP, and two molecules of NADH.
Thus, the correct answer is 'puruvate' as it is the main product of glycolysis, along with ATP and NADH molecules.
