Question

Which does not pertain to facilitated transport

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

Answer 1

The correct option is C Uphill transport

Properties of facilitated transport are:

1. They need special carrier proteins hence a need for a specific type of membrane.

2. As the gradient is achieved equal on both sides saturation is achieved and no more transport takes place.

3. It is highly selective.

4. The transportation is downhill and in favour of the concentration gradient.

So the correct answer is 'Uphill transport'.
