Totals per molecule of glucose Remember - pyruvate has 3 carbons 1/3/2019 Totals per molecule of glucose Remember - pyruvate has 3 carbons ATP _______ NADH _______ FADH2 _______ Where’s the oxygen? CO2____

Chemiosmosis Electron Transport Chain (system) 1/3/2019 Chemiosmosis Electron Transport Chain (system) Occurs on the inner membrane of the mitochondrion Takes high energy electrons from NADH and FADH2 and transfers it to ATP is the process of making water from excess Hydrogen ions, oxygen, and electrons (depleted of energy)
