Question

facilitated diffusion occurs________. multiple choice into the cell only out of the cell only in either direction depending on the temperature in either direction depending on the concentration gradient of the molecule

Explanation:

Facilitated diffusion is a passive - transport process. It moves substances across the cell membrane with the help of transport proteins. The direction of movement is determined by the concentration gradient of the molecule, moving from an area of higher concentration to an area of lower concentration, which can be into or out of the cell.

Answer:

D. in either direction depending on the concentration gradient of the molecule
