Determine if the following statement is true or false. If true, choose TRUE. If false, choose the rewording that is true. Cell membrane proteins transmit information in the cell and aid in cell movement.
A. Cell membrane proteins transport substances across the membrane and aid in protein synthesis.
B. Cell membrane proteins transmit information in the cell and transport substances across the cell membrane.
C. Cell membrane proteins store wastes and form the outer layer of the cell membrane.
D. TRUE

The statement is false and correct answer is B. Cell membrane proteins transmit information in the cell and transport substances across the cell membrane.

Explanation:

Cell membrane proteins are embedded in the cell membrane and different proteins have different functions. These proteins are important in maintaining the right amount of important molecules in the cytoplasm of the cell.

Some proteins help in the communication of cells. These proteins bind to the signal molecule coming from outside and inside the cell and then bring a conformational change in them. This conformational change activates signal molecule which activates the membrane transport protein.

Then these membrane transport proteins transport substances across the cell membrane. These proteins are also called carrier proteins. Therefore the correct answer is B. Cell membrane proteins transmit information in the cell and transport substances across the cell membrane.
