思路分析
We start by identifying which membrane components are responsible for the listed functions, using standard cell membrane biology concepts.
1) Receptor sites: The binding of signals to receptors is a function typically carried out by membrane proteins, which provide specific binding sites for ligands. Therefore, proteins are responsible here.
2) Channel formation: Creating passageways for ions and molecules across the membrane is a hallmark of membrane proteins that ......Login to view full explanation登录即可查看完整答案
