Q. Which does not pertain to facilitated transport :
- Uphill transport
- High selectively
- Transport saturation
- Requirement of special membrane proteins
Solution :
Correct option : A Facilitated transport is the movement of molecules across a membrane through special transport proteins. The movement is in accordance with the concentration gradient and hence a downhill transport. Transport proteins provide high selectivity and transport only certain molecules. Example: Ion channels, aquaporins, etc. So the correct answer is ‘Uphill transport’.
