The proteins in the cell membrane that can open and close are called:
A) enzymes.
B) gated channel proteins.
C) glycoproteins.
D) both A and B.

Question

Quizplus · Accepted Answer

Gated channel proteins are proteins embedded in the cell membrane that can open and close, regulating the flow of ions or molecules into and out of the cell. Enzymes are not typically involved in this process. Glycoproteins are involved in cell signaling and recognition, but do not regulate the flow of materials across the membrane. Therefore, B is the best choice as it is the only option that accurately describes the function of these proteins.
