If the concentration of phosphate in the cytosol is 2.0 mM and the concentration of phosphate in the surrounding fluid is 0.1 mM, how could the cell increase the concentration of phosphate in the cytosol? a) passive transport b) diffusion c) active transport d) osmosis e) facilitated diffusion

    so that is taking a lower concentration to higher concentration

    which one moves against the gradient?

    diffusion moves from higher concentration to lower concentration.

    Yeah. I can't figure out whether it's B or E

    Diffusion moved down the concentration gradient. you are looking for what moves up the concentration gradient.. from low to high.

    thus it will expend energy

    facilitated diffusion is a passive process that takes transport proteins to cross the membrane

    Ohhh. I thought it meant the 2.0 was distributing to balance out the 1.0. So it's not diffusion...that's two answers down

    Active transport moves against the concentration gradient

    and osmosis equalizes through the semipermiable membrane.

    though it does move solutes from a low concentration to a high concentration. hope i Helped. good luck :)
