Answer 15

In the cell

Question 16

The breakdown of fatty acids, by alpha and beta pairs, at the cost of 1 ATP each

Answer 16

Beta-Oxidation

Question 17

Amino acids can be broken down into three things, what are they?

Answer 17

1. Glucose
2. Ketone bodies
3. Acetyl-CoA

Question 18

How many Acetyl-CoA can the body process at a time?

Answer 18

1

Question 19

What do ketone bodies do to the blood?

Answer 19

Lower PH

Question 20

What happens to pyruvate in an aerobic environment?

Answer 20

It turns into Acetyl-CoA and is sent into the Krebs cycle
