Mitochondria

Question 1

How are mitochondria similar to bacteria?

Answer 1

• Have their own DNA
• Have their own protein synthesis system and ribosomes
• Make ATP!

Question 2

3 stages of ATP production

Answer 2

1) citric acid cycle
2) electron transport chain (respiration)
3) oxidative phosphorylation

Question 3

citric acid cycle

Answer 3

Starting product is oxolacetate
Produces CO2
NAD+ and FAD reduced to NADH and FADH2

Question 4

CCCP

Answer 4

uncouples release of protons (favorable) with ATP synthesis (unfavorable) so no ATP is produced
&raquo_space; eliminates proton gradient

Question 5

oxidative phosphorylation

Answer 5

protons flow into inner membrane which ATP synthase uses to make ATP

Question 6

why is it called oxidative phosphorylation?

Answer 6

ADP is phosphorylated and pyruvate is oxidized

Question 7

electron transfer chain

Answer 7

electrons are transferred through a series of pumps that release energy from the high-energy electrons that is used to pump H+ out of the inner membrane

Question 8

coenzymes

Answer 8

NAD+/NADH and FAD/FADH2 both store chemical energy
