Which of the following transport mechanisms shows saturation of transport but does not show uphill transport?

Options

  1. ASimple diffusion
  2. BActive transport
  3. CFacilitated diffusion
  4. DBoth simple and facilitated diffusion

Correct answer

C. Facilitated diffusion

Step-by-step solution

Facillitated diffusion is helped diffusion of molecules from the region of their higher concentration to their lower concentration, with the help of trans membrane or channel proteins. Since carrier proteins are involved it shows saturation of transport when all carrier proteins are involved in the movement.
