Where does glycolysis occur?

Glycolysis is a metabolic pathway that occurs in the cytosol of cells. It is the process by which glucose is broken down into smaller molecules, producing energy in the form of ATP (adenosine triphosphate) and NADH (nicotinamide adenine dinucleotide).

Glycolysis is an anaerobic process, meaning it does not require oxygen. It is the primary means of generating ATP in the absence of oxygen, and it occurs in many types of cells, including muscle cells, red blood cells, and cells in the liver and brain.

During glycolysis, a molecule of glucose is broken down into two molecules of pyruvate, producing a small amount of ATP and NADH. If oxygen is present, the pyruvate can be further broken down in the mitochondria through the process of aerobic respiration, which generates a larger amount of ATP.


Glycolysis is an important metabolic pathway that plays a crucial role in the production of energy in cells. It is regulated by enzymes and a number of signaling pathways, and it is regulated by various hormones and other signaling molecules.
