Question

Active transport of solutes across a membrane ____ energy input, and ____ need the involvement of membrane proteins. It transports solute _______ its electrochemical gradient. (1): needs/ (2): does not need; (3): does/(4): does not; (5): following/(6) against

A)2, 3, and 5

B)2, 3, and 6

C)1, 3, and 5

D)1, 3, and 6

E)1, 4, and 6

Answer 1

active transport requires energy input proteins in the plasma membrane helps in the transport of molecules against the concentration gradient with the input of energy is called active transport.

Active transport of solutes across a membrane needs (1) energy input and does (3) need the involvement of membrane proteins. It transports solute against (6) its electrochemical gradient

so the answer is D) 1,3and 6
