The selective permeability of a phospholipid bilayer membrane can be increased with help from ________ proteins.

Question

Quizplus · Accepted Answer

Transport proteins, channel proteins, and passive carrier proteins can all help increase the selective permeability of a phospholipid bilayer membrane. Transport proteins can actively transport molecules across the membrane, while channel proteins create pores that allow certain molecules to pass through. Passive carrier proteins facilitate the diffusion of molecules across the membrane without requiring energy. Therefore, the best choice is D, since it includes all three types of proteins.
