Question

Which of the following does not require carrier molecules during transport through cell membranes? (A) simple diffusion (B) facilitated diffusion (C)  Na+-K+ transport (D) none of these

Tardigrade Admin · Accepted Answer

Simple diffusion i.e. Movement of molecules from higher concentration to lower concentration does not require carrier molecule for transport through cell membrane.
