Question

The processes of diffusion and transport are both used to?

1) break down molecules to release energy
2) move molecules into or out of cells of the body
3) bring molecules into cells when they are more concentrated outside of the cell
4) move molecules against a concentration gradient, using ATP molecules

Answer 1

3) bring molecules into cells when they are more concentrated outside of the cell

it's passive transport so molecules move from an area of high concentration to low concentration without the use of energy
