Question

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? View Available Hint(s)

Answer 1

The cell could increase the concentration of phosphate in the cytosol by active transport.

Step-by-step explanation:

There is a concentration gradient when the particle concentration is higher in one place than in another. In passive transport, the particles diffuse in favor of the concentration gradient, from areas of greater concentration to areas of lower concentration, until they are equally distributed.

In active transport, unlike the passive one, energy is spent to move a substance against its concentration gradient.
