28.關於真核生物細胞膜相關的敘述，下列何者錯誤？
(A)鈉鉀泵(Na+/K+-ATPase pump)是一種配體門控離子通道(ligand-gated ion channel)
(B)嵌入蛋白(integralproteins)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)
(C)膜蛋白(membraneproteins)附著於或鑲嵌在磷脂雙層
(D)擴散(diffusion)是分子的從高至低濃度的區域的移動

(A)(Na+/K+-ATPase pump)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 of energy, and proteins responsible for cell adhesion.  

Examples of integral membrane proteins:

• Insulin receptor
• Some types of cell adhesion proteins or cell adhesion molecules (CAMs) such as integrins, cadherins, NCAMs, or selectins
• Some types of receptor proteins
• Glycophorin
• Rhodopsin
• Band 3
• CD36
• GPR30
• Glucose Permease
• Ion channels and Gates
• Gap junction Proteins
• G protein coupled receptors (e.g., Beta-adrenergic receptor)
• Seipin
