The pentose phosphate pathway, an alternative to glycolysis, is used to catabolize five carbon sugars. One ATP molecule and 12 NADPH molecules are produced from one glucose molecule. Glycolysis is the most common pathway for the oxidation of glucose. Two pryuvic acid molecules are the end product. There is a net gain of two ATP molecules and two NADH molecules per molecule of glucose oxidized through glycolysis.

Pyruvic acid loses one carboxyl group, and CO2 is a byproduct, during the transition step. Two carbon acetyl groups are oxidized in the Krebs cycle. Electrons are picked up by NAD+ and FAD for the electron transport system.
