Answer 22

2

Question 23

Where does Pyruvate Oxidation occur?

Answer 23

In the Mitochondria

Question 24

Before the Citric Acid Cycle, what breaks off from the 2 acetyl CoA?

Answer 24

Coenzyme A and 4CO2

Question 25

Answer 27

2 ATP, 6NADH, 2FADH2

Question 28

In the ETC, when electrons are delivered to the proteins, what initially happens to them?

Answer 28

The electrons are passed off like a relay race and move through the ETC

Question 29

True or False? Having excess H+ is good.

Answer 29

False

Question 30

How is excess H+ reduced?

Answer 30

The H+ binds to the ATP synthase and turn its 'motor' so it can bind to the ADP and add a phosphate to create ATP
