2. Glycolysis Takes place in cytoplasm Aerobic and anaerobic cycle
Yeilds:
ATP= 4 gross; 2 net
NAD= 2 NADH (goes to electron transport chain, ETC)

4. Glycolysis

5. Kreb’s Cycle Pyruvate enters the cycle Occurs in mitochondrial matrix
Yeilds:
ATP= 1 per pyruvate cycle
NAD= 6 NADH
FAD= 2 FADH2
NADH and FADH2 go to ETC

6. Kreb’s

7. Electron Transport Chain
Occurs in inner membrane of mitochondria
Hydrogen and electrons are carried along chain to transfer energy
Electrochemical gradient = ATP
O2 is the final electron accepter in the form of H2O

8. ETC

9. ETC Complexes

10. ATP Synthase Protein Complex
Contains a rotor, rod, and knob
Rotor spins clockwise when H+ flows though
Rod begins to spin activating the catalytic sites in the knob
Knob contains catalytic sites that join ADP to inorganic phosphate to make ATP
