Vedclass · Answer

(C) Membrane channels are specialized integral membrane proteins that facilitate the transport of specific molecules or ions across the cell membrane.$1$. They are indeed proteins.$2$. They are usually gated, meaning they can switch between open and closed states to regulate transport.$3$. The statement "All ions pass through the same type of channel" is incorrect because channels are highly selective; for example, potassium channels only allow potassium ions to pass, and sodium channels only allow sodium ions to pass.$4$. Porins are specific types of channel proteins that form large pores in the outer membranes of plastids, mitochondria, and some bacteria, allowing the passage of molecules up to the size of small proteins.
