(A)(Na+/K+-ATPasepump)是一種配體門控離子通道(ligand-gated ion channel)主動運輸幫浦蛋白不屬於離子通道(離子通道為促進性擴散)(B)嵌入蛋白(integral proteins)的存在,讓細胞膜對不同物質或分子具有選擇性滲透性 (selectively permeable) An integral membrane protein (IMP) is a type of membrane protein that is permanently attached to the biological membrane. All transmembrane proteins are IMPs, but not all IMPs are transmembrane proteins.IMPs include transporters, linkers, channels, receptors, enzymes, structural membrane-anchoring domains, proteins involved in accumulation and transduction o...
