need a better idea about active transport and carrier proteins n whether partially permeable membrane is necessary for active transport?

well, think of it this way, you're on a boat on a river and the engine is not on and you're following the current of the river. It requires no energy
Now, you wish to move against the current. So you must turn on the engine and use thrust power, thus using energy. Hence, active transport.

and no, partially permeable membrane is not necessary for active transport. It requires energy .
(Correct me if i'm wrong)

Hope i helped.

Its not a necessity the partially permeable membrane for active transport and it does happen even with it so u are correct !

i still didn't get the carrier protein part

can some1 list for me the layes of the eye plzzzzzzzzz?????????

 

[malay]

can some1 list for me the layes of the eye plzzzzzzzzz?????????

its *layers i guess
1.innermost is RETINA
2.CHOROID
3.SCLERA (white of the eye) but in pprz we usually get CORNEA to label
4.CONJUCTIVA

for better understanding check this out http://www.google.com.pk/imgres?hl=...=204&start=0&ndsp=13&ved=1t:429,r:12,s:0,i:95

guys can u guess the A grade on biology 62 this year?

 

[aj shahzad]

can someone provide atomic physics notes plzz its urgent ....i just found that i know nothing about star formation !!!!

 

[SalmanPakRocks]

I uploaded star formation lots of times, here it is again for u.

Its gonna be pretty high i guess with the amt of people ive seen saying the paper was the best they had given ever in their life

well the percentile is set after all the papers have been marked . So if p1 and p2 will be difficult than it will fall!

how does boiling a sample of potato affect the rate of osmosis?? nd why?
just the general concept...

it increases the rate maybe because it increases the movement of molecules.
Correct me if i'm wrong
