Answer 11

glycolysis

Question 12

What is the overall goal of making lactic acid?

Answer 12

to make ATP when there is no O2 present

Question 13

How do you process lactic acid once you use it?

Answer 13

Kory cycle

Question 14

How do we use proteins for metabolism?

Answer 14

Rip off NH2 (amine group) and throw it into glycolysis or krebs

Question 15

How is lactic acid processed in the blood?

Answer 15

Dumped into the blood and picked up by liver, converts lactic acid back to glucose using ATP

Oxidative reanimation:

Answer 16

Ripping off amine group

Question 17

What happens to the amine group once it is ripped off protein?

Answer 17

Amine group turns into ammonia then urea to pee it out

Where does glycolysis occur?

Answer 35

In the cytosol

Question 36

Why do we need O2 for krebs?

Answer 36

Because it is in the mitochondria

Question 37

Glycolysis:

Answer 37

- occurs in cytoplasm - no O2 needed - anaerobic metabolism
