Vedclass · Answer

(C) Membrane channels are specialized integral membrane proteins that facilitate the movement of specific molecules or ions across the lipid bilayer.Statement $A$ is correct: Channels are composed of proteins.Statement $B$ is correct: Many channels are gated,meaning they can switch between open and closed states to regulate transport.Statement $C$ is incorrect: Membrane channels are highly selective. Different ions (e.g.,$Na^+$,$K^+$,$Ca^{2+}$) require specific types of channels to pass through the membrane.Statement $D$ is correct: Porins are large channel proteins that form huge pores in the outer membranes of plastids,mitochondria,and some bacteria,allowing the passage of molecules up to the size of small proteins.
