Electron Transport Chain (ETC)

Question 1

Where is ETC found

Answer 1

Inner membrane of mitochondria

Question 2

Aerobic of anaerobic?

Answer 2

Aerobic

Question 3

What is the purpose of ETC

Answer 3

To use oxygen and high energy electrons to produce a LOT of ATP

Question 4

Reactants of ETC

Answer 4

10 NADH
2 FADH
6 O2

Question 5

Products of ETC

Answer 5

26-28 ATP
6 H2O

Question 6

Describe chemoismosis

Answer 6

H+ gradient across membrane drives cellular work

Question 7

What is ATP synthase

Answer 7

Enzymes that makes ATP use energy from proton (H+) gradient- flow of H+ back across membrane

Question 8

4 steps of ATP

Answer 8

1) NADH and FADH2 donate high energy electrons to the ETC
2) energy from electrons are used to pump H+ against concentration gradient
3)oxygen accepts electrons from ETC and combines with H+ to form water
4)H+ travels through ATP synthase, causing it to spin- spinning allows a phosphate group to bond with ADP, making ATP (chemiosmosis)
