what diffuse through carrier protein?

[paramedicrider]

Yes i am young but i wish to learn A level Bio very much. Can any 1 tell me Generally what diffuse through carrier protein. Exampels that i know : Na+, Ca2+,K+, glucose. What else????

[thank.darwin]

Small polar molecules... that can't get through by simple diffusion due to the phospholipid tails - Larger molecules would enter through endocytosis... Does that help?

endocytosis?...??
Entry of molecules by endocytosis? are U talking about receptor mediated endocytosis,
I haven't heard of such a consequence........
