What do facilitated diffusion and active transport have in common?
A) Both involve transport of a solute up its concentration gradient.
B) Both involve transport of a solute down its concentration gradient.
C) Both involve the use of energy provided by ATP.
D) Neither require ATP to function.
E) Both are examples of carrier-mediated transport.

Question

Quizplus · Accepted Answer

Both facilitated diffusion and active transport involve carrier proteins that aid in the transport of molecules across a membrane. Facilitated diffusion moves molecules down their concentration gradient, while active transport moves them against their concentration gradient with the use of energy. However, both processes require carrier proteins to bind to and transport the molecules across the membrane.
