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 !

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 :p :p

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
