Electron Transport Chain

Question 1

Big concepts

Answer 1

1. Electron carriers are in short supply

2) ADP in short supply

3) ATP is stable

4) Inner mitochondrial membrane is impermeable to protons

5) Protons ONLY flow into the matrix if ATP is being made

6) Proton pump doesn’t work if proton gradient very high

7) No proton pumping = no electron movement down ETC
