Q

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

A

Amine group turns into ammonia then urea to pee it out

18
Q

How do we use fats?

A

Snap off glycerol from fatty acid tails

19
Q

What is the plugging and chugging cycle of glycerol called?

A

Beta oxidation

20
Q

Acytl coa to ketones is called:

A

Ketosis or ketogenesis

21
Q

What makes ketones?

A

Liver

22
Q

What is resting membrane potential?

A

-70

23
Q

What is potassium’s equilibrium?

A

-90

24
Q

Leak channels limit:

A

sodium intake and rate of diffusion

25
Q

More leak channels for:

A

K+

26
Q

K+ moves:

A

out of the cell

27
Q

Na+ moves:

A

into the cell

28
Q

What makes the inside of the cell more positive?

A

pump + Na+ leak channels

29
Q

What creates an action potential?

A

If the Na+ v.g.c hits threshold

30
Q

What is the difference between catabolism and anabolism?

A

Catabolism is ripping apart proteins and anabolism is building proteins up

31
Q

Order in which our body breaks things down?

A
  1. carbs/glucose
  2. lipids
  3. proteins
32
Q

What do you make as a bi product of metabolism?

A

Co2

33
Q

What is used to make mitochondria?

A

O2

34
Q

What is the goal of metabolism?

A

To make O2/ATP then Co2 as a bi product

35
Q

Where does glycolysis occur?

A

In the cytosol

36
Q

Why do we need O2 for krebs?

A

Because it is in the mitochondria

37
Q

Glycolysis:

A
