Explanation / Answer

Ans-40

Sodium-potassium ATPase pump involve in transportation(active transport) process. In our question all protein like like transmembrane protein,integral protein etc make a channel for transportation , but consumer of energy, requre only requre only respiratory enzyme for obtaining energy ,do not require sodium potasium channel for transportation like sodium potassium ATPase.So our ans is (E).
