Question
Chapter 4.5, Problem 5MC
Summary Introduction
To determine:
Distinguish among simple diffusion, facilitated diffusion and active transport.
Introduction:
In diffusion, the particle moves across the membrane from higher to lower concentration. In simple and facilitated diffusion there is no use of energy where else active transport uses energy like ATP.
