Answer: Glycolysis occurs outside the mitochondria in the cytoplasm of the cell.
Glycolysis is a metabolic process in which glucose is broken down into two molecules of pyruvate ( 3 carbon containing molecule) and produces energy molecules as 2 ATP ( adenosine triphosphate) and 2 NADH molecules. Glucose is one of the most important energy fuel that is utilized by living organisms.
Glycolysis occurs in the cytoplasm of all living cells. Thus, it occurs outside the mitochondria.
