The process of facilitated diffusion is important to:
A)permit exchange of gases in the lungs
B)enable cells to take in water
C)enable most body cells to take in glucose
D)permit cells to secrete their products

Question

Quizplus · Accepted Answer

Facilitated diffusion is a type of passive transport that involves the movement of molecules or ions across a membrane with the help of a transport protein. In the case of glucose, facilitated diffusion occurs through specific glucose transporters in the membrane, allowing most body cells to take in glucose for energy production. Therefore, choice C is the correct answer. Choice A involves diffusion of gases such as oxygen and carbon dioxide through simple diffusion, not facilitated diffusion. Choice B may involve facilitated diffusion of water through specific aquaporin channels, but the question only refers to facilitated diffusion in general. Choice D involves secretion, which is an active transport process, not facilitated diffusion.
