How do materials move into and out of the cell?

Question

pls answer this question...tnx!GODBLESS!!..

Answer 1

very very well outlined by tralala

Answer 2

There are three processes included in the transfer of materials:

1. Active transport: this is when materials is transferred from low concentrations of solute to high concentration of solutes, with the use of ATP

2. Passive transport

a. diffusion - transfer of small nonpolar molecules from high to low concentrations, simply by going in and out of the cell membrane

b. facilitated diffusion - transfer of molecules from high to low concentrations with the use of proteins as passageway canals

c. osmosis -flow of water from low concentration of solutes to high concentration

3. Endocytosis

a. Phagocytosis - pseudopods of cell membrane eat up large molecules from the environment

b. Phinocytosis - pseudopods of cell membrane "eat" fluids in the environment

c. Endocytosis with receptor - selectively transfer large molecules

Answer 3

through the cell membrane by diffusion, facilitated diffusion and active transport
