9/26/2020 Electron Transport Chain Series of enzymes on mitochondrial membrane • Gain 32 ATP from the release of energy from • FADH 2 (Krebs)- 4 ATP • NADH (Krebs)- 24 ATP • NADH (Glycolysis) 4 ATP • Oxygen is the final electron acceptor – Has to be present to change NADH, FADH 2 to NAD+ and FAD 9

9/26/2020 ATP synthesis • Occurs along the membranes in both the chloroplast and mitochondria • The electron transport chain creates a concentration gradient between eand H+ • Water is final product 10

9/26/2020 Animations • Community College of Baltimore County • Smith College • Virtual Cell Animation 11

9/26/2020 • H+ inside and e- outside (H+ cannot go through membrane) • ATP synthetase – The energy from their passing through is used as the energy needed to make ADP + P ATP • When 2 H+, 2 e- and oxygen (final electron acceptor) all meet outside the membrane, water is formed 12

9/26/2020 Chemiosmosis • Formation of ATP in chloroplasts and mitochondria 13

9/26/2020 14

9/26/2020 Energy Flow • Follow the energy from the sun to the end of chemiosmosis 15
