Glycolysis is the process by which the body produces ATP from Glucose.
The Glucose is first broken apart (Lysis). This allows for one set of enzymes to work on both halves of the Glucose, thus allowing for greater efficiency.
Carbon one of the triose glyceraldehyde is then oxidized. The result is Glycerate
The oxidized triose is then reduced. The hydroxyl group is removed, leading to lactate. Furthur reduction is aerobic, as NAD+ is reused for further oxidization.
Pyruvate molecules are then converted to acetyl coenzyme A and hydrogen and carbon dioxide are released.
