END PRODUCTS OF

GLYCOLYSIS• 2 PYRUVATE MOLECULES – moves into mitochondrium matrix

• 2 NET ATP – Usually stays in cytoplasm to be used by the cell

2 used as activation energy (GLUCOSE ACTIVATION)

4 made when producing pyruvate (ENERGY HARVEST)

• 2 NADH – High energy compound that moves to e- transport chain.
