Question

What is a major difference between facilitated diffusion and active transport?

Answer 1

Answer:

Major difference between active transport and facilitated difusion is:

Active transport moves substances against the concentration gradient.

Facilitated diffusion moves molecules through the plasma membrane.

Explanation:

• Active transport involves the transport of molecules against the concentration gradient.
• Since molecules move from lower concentration to higher concentration this mode of transport needs energy.
• Facilitated diffusion do not require energy  but need some other molecule or carrier protein to transport the molecules across the membranes.
• In facilitated diffusion, the molecules move from their region of higher concentration to the region of lower concentration.
