#1 is tricky.

 

[Mstoothlady2012]

#1 is tricky.

so is #5...no1 has gotten that one correct so far

 

[harrygt]

5 is C then. I am sure glucose reabsorption is done only in proximal tubules.
A must be wrong, because you put NO reabsorption.
Reabsorption of glucose still happens, but it is less to get rid of some. However, I'm not sure this is because lack of glucose carriers.

yup, you got my hint. Since the glucose level is so high, you need more carriers for reabsorption. But your body can't work that fast and produce higher amount of carriers than the normal level in short period of time. Hence some of the glucose escape in the filtrate.

Thanks! I got it. GOOOOOOOOOD point!

That's the first time you ever accepted my explanation w/o arguing. I swear I would have gone nuts if you had argued back to prove me wrong

 

[harrygt]

Lol, I'm sorry if I have been a lil bold on the previous argument. I really could not help it with the Gchem question. I hope you got that one.

 

[Mstoothlady2012]

Well to be honest, I still don't agree with you. But as you can see, I am not very good at arguing. So why bother?

 

[harrygt]

Lol, your bad! You gotta read my argument without letting your previous way of solving the problem affect you at that moment.
I have bunch of 95% similar questions to that one in my Gchem notebood [only the compound and the numbers are different]. My teach did not use the coefficients of the ion that we add to the solution at all as it completely makes sense for me. Check it, try to understand, and ask me the part that you don't get. I will definitely help you.

 

[smile101]

so is #5...no1 has gotten that one correct so far

good to know you are a desi too..

anyways, is the answer to #1 E??

 

[Mstoothlady2012]

anyways, is the answer to #1 E??

no its C

 

[Mstoothlady2012]

no its C

yea it is too much for me to put cyanocobalamin instead of B12😀 Anyways yea folic acid & B12 are imp for blood cells growth & formation.

Not sure about #1

 

[DRHOYA]

Can someone explain these "peritubular" capillaries?? I put Glomerulus for that question....but everyone else seems to put "peritubular". I thought the Glomerulus absorbed alot of the material before the filtrate moved to the proximal convuluted tubule?

Glomerulus is only the part with lots of convoluted capillaries inside the Bowman's capsulae. An efferent arteriole comes out of the glomerulus [and the capsule] which surrounds the proximal and distal tubules + loop of Henle. The surrounding capillaries are responsible for reabsorbing stuff from the mentioned areas, and also secreting stuff from blood into these parts of the nephron. The surrounding capillaries of proximal and distal tubules is called peritubular capillaries. The ones surrounding the loop of Henle is called Vasa Recta.
I hope this will help you DRHOYA>

Yeah ok, I get it now. So what the question was asking is "what is REPSONSIBLE for the absorbtion".....which would be peritubular capillaries. I answered wrong by thinking "where in the nephron is absorption occuring"....thus why I chose Glomerulus over the other choices. Thanks man.

Boy, You are still missing sth here. Let me point out first that it is called REabsorption.
Second, reabsorption occurs everywhere in the nephron, depending on the type of the stuff reabsorbed. The glomerulus is only responsible for filteration. The answer would still be the same if you were asked: WHere in the nephron is absorption occuring". Look glomerulus up in Wiki. It might help getting rid of the confusion.

 

[harrygt]

Look at it this way! Things only get out at Glomerulus during filtration.
Later, you have reabsoption in prximal tub, Loop of H, distal tub, and collecting duct.

 

[DRHOYA]

Ohhh ok. I was seeing the words filtration and reabsorption as the same thing. I see. The glomerulus is filtering the blood coming in due to high pressure. Reabsorption is happening at all parts of the nephron....that I know. And the peritubular capillaries are responsible for the reabsorption occuring at parts of the nephron.
