Active transport

Facilitated diffusion
|
|
|
Both simple and facilitated diffusion
|
Detailed explanation-1: -Which of the following transport mechanisms shows saturation of transport but does not show uphill transport? Facilitated diffusion and active transport both shows transport saturation.
Detailed explanation-2: -Facilitative transport is strongly selective since the transport of any specific molecule or ion involves carrier proteins. Thus, the correct answer is Option D, i.e., Uphill transport.
Detailed explanation-3: -Active transport – Does not show uphill transport.
Detailed explanation-4: -Facilitated diffusion involves downhill (higher to lower concentration) movement of molecules with the help of special membrane proteins.
Detailed explanation-5: -Since facilitated diffusion and active transport both use transport proteins, transport saturation can be seen here.
