Quiz 3 Flashcards
The brain prefers:
Glucose and ketones
What grabs acid from ketones?
Bicarbonate and albumin
What is the first step in using glucose?
Glycolysis
What do you use to start glycolysis?
Glucose
How many atp do we make and net?
4 atp
2 atp
How many ATP’s are made at kreb’s?
2 atp
How many NADH made in kreb’s + connector step?
6 in krebs
2 in connector step
How many NADH at glycolysis?
2 nadh
What gives you the most ATP?
electron transport chain and aerobic metabolism
aerobic:
krebs+ electron transport chain
anaerobic:
glycolysis
What is the overall goal of making lactic acid?
to make ATP when there is no O2 present
How do you process lactic acid once you use it?
Kory cycle
How do we use proteins for metabolism?
Rip off NH2 (amine group) and throw it into glycolysis or krebs
How is lactic acid processed in the blood?
Dumped into the blood and picked up by liver, converts lactic acid back to glucose using ATP
Oxidative reanimation:
Ripping off amine group
What happens to the amine group once it is ripped off protein?
Amine group turns into ammonia then urea to pee it out
How do we use fats?
Snap off glycerol from fatty acid tails
What is the plugging and chugging cycle of glycerol called?
Beta oxidation
Acytl coa to ketones is called:
Ketosis or ketogenesis
What makes ketones?
Liver
What is resting membrane potential?
-70
What is potassium’s equilibrium?
-90
Leak channels limit:
sodium intake and rate of diffusion
More leak channels for:
K+
K+ moves:
out of the cell
Na+ moves:
into the cell
What makes the inside of the cell more positive?
pump + Na+ leak channels
What creates an action potential?
If the Na+ v.g.c hits threshold
What is the difference between catabolism and anabolism?
Catabolism is ripping apart proteins and anabolism is building proteins up
Order in which our body breaks things down?
- carbs/glucose
- lipids
- proteins
What do you make as a bi product of metabolism?
Co2
What is used to make mitochondria?
O2
What is the goal of metabolism?
To make O2/ATP then Co2 as a bi product
Where does glycolysis occur?
In the cytosol
Why do we need O2 for krebs?
Because it is in the mitochondria
Glycolysis:
- occurs in cytoplasm
- no O2 needed
- anaerobic metabolism
Krebs cycle:
- occurs intermembrane
- O2 needed
- aerobic metabolism
1 Nadh=
3 ATP
Adult cells produce:
36 ATP -2 in glycolysis \_\_\_\_\_\_\_\_\_\_\_\_ mitochrondira=34 ATP -2 in krebs \_\_\_\_\_\_\_\_\_\_ 32 ATP
What makes up RMP?
Na+/K+ ATPase pump + Na+ leaking in and K+ leaking out
