Question

In carrier-mediated diffusion, molecules move from a region of:

Options

• Higher concentration to lower concentration with the use of energy.

• Higher concentration to lower concentration without the use of energy.

• Lower concentration to higher concentration with the use of energy.

• Lower concentration to Higher concentration without the use of energy.

Answer 1

Higher concentration to lower concentration without the use of energy.

Explanation:

The transfer of molecules from a location of higher concentration to a region of lower concentration is referred to as carrier-mediated diffusion.
