Question

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

Question 3 options:

Active transport moves substances against the concentration gradient.

Active transport uses proteins in the process.

Facilitated diffusion moves molecules through the plasma membrane.

Facilitated diffusion requires large amounts of energy.

Answer 1

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.

Step-by-step 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.
