What is required for diffusion to occur?
A) protein carrier or channel

C) ATP
D) solute pump
E) ribosomes

Question

Quizplus · Accepted Answer

Diffusion requires a concentration gradient, where there is a difference in the concentration of a substance between two areas. This allows the substance to move from an area of high concentration to an area of low concentration, without the need for a protein carrier or channel, ATP, solute pump, or ribosomes.
