Question

What does the process of diffusion do for the cell?


A.
moves energy in the cell


B.
moves oxygen through the cell membrane


C.
moves water in and out of the cell


D.
moves proteins through the cell membrane

Answer 1

Energy is created in the cell itself. Oxygen needs to be dissolved in order to move across the membrane. Proteins are generally too large to pass through the membrane.

Water, however, is in constant diffusion in and out of the cell to provide for an osmotic balance. So the answer is C
