OXIDATIVE PHOSPHORYLATION

Occurs across where and through what?

Inner mitochondrial membrane and electron transport chain

Step 1

NADH and FADH2 reduce first and second carrier proteins by donating electrons, releasing protons into intermembrane space

Step 2

Electrons passed from carrier to carrier in a series of redox reactions

Step 3

Energy released from reactions used to pump protons into intermembrane space

Step 4

Protons flow through chemiosmotic channel down their concentration gradient

Step 5

Enough energy released to enable ATP synthase to produce 1 ATP from ADP and Pi

Step 6

Oxygen acts as final hydrogen acceptor, producing water
