Question

Which does not pertain to facilitated transport?

• A. Uphill transport
• B. High selectively
• C. Transport saturation
• D. Requirement of special membrane proteins

Answer 1

The correct option is A Uphill transport

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'.
