Read the following statements and find out the incorrect statement.

Options

A. Different proteins in the membrane play a major role in both active as well as passive transport.
B. Pumps are the proteins that use energy to transport substances across the cell membrane from a low concentration to high concentration (downhill transport).
C. Like enzymes the carrier protein is very specific in what it carrier across the membrane.
D. Diffusion whether fcilitated or not-takes place only along a gradient and do not use energy.

Answer

B

Explanation

Different proteins in the membrane play a major role in both active as well as passive transport.
Pumps are the protein that use energy to transport substances across the cell membrane from a low concentration to high concentration (uphill transport)
Like enzymes the carrier proteins is very specific in what it carries across the membrane.
Diffusion whether facilitated or not takes place only along a gradient and do not use energy.
