E)Large molecules diffuse faster than small molecules.

Question

Quizplus · Accepted Answer

Diffusion through a membrane is a passive process and depends on random motion. There are no active forces involved in diffusion. The rate of diffusion is inversely proportional to the membrane's surface area, not directly proportional. Ions move from a higher concentration to a lower concentration in diffusion. Larger molecules diffuse more slowly than smaller molecules due to their size and molecular weight.
