What is a major difference between facilitated diffusion and active transport?
question 30 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.

The correct option is A) Active transport moves substances against the concentration gradient.

Explanation:

The major difference between active transport and facilitated diffusion is that active transport uses energy whereas the process of facilitated diffusion does not require energy. This is because in active diffusion, molecules move against the concentration gradient from an area of lower concentration to an area of higher concentration. During facilitated diffusion, molecules move from an area of higher concentration to an area of lower concentration with the help of other molecules along the concentration gradient.
