3. Location: Along the inner membrane of the mitochondria (cristae)
Involves a number of enzymes embedded in the cristae
Products (NADH and FADH2) of glycolysis and the Krebs Cycle are in the cristae

4. Step 1
NADH and FADH2 give up electrons to a protein (NADH dehydrogenase)

5. Step 2
The electrons provide energy to move H+ ions across the cristae from the inner compartment to the outer compartment.

6. Step 3
H+ ions travel through the enzyme ATP synthase, causing the bottom to spin
The spinning provides energy to attach a phosphate group onto ADP, creating ATP
