Question

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

Answer 1

Answer:

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

Explanation:

Facilitated diffusion can be described as the type of diffusion which occurs with the help of other molecules. For example, when integral proteins help in the transport of a molecule through the cell membrane. Facilitated diffusion is a type of passive transport as it allows molecules to move from an area of higher concentration to an area of lower concentration along a concentration gradient.

Active transport is the movement of molecules against the concentration gradient from an area of lower concentration to the area of higher concentration and hence, require energy.
