Question

State whether the following statements are true or false.
Carrier proteins are necessary for active transport to occur.

• A. True
• B. False

Answer 1

The correct option is A True

Carrier proteins are those which facilitate diffusion of molecules across the cell membrane, they allow movement of molecules in and out of the cells against the concentration gradient. Active transport requires carrier proteins also called as pumps. They need ATP energy because the transport is uphill, against the concentration gradient.

So, the correct answer is 'True'.
