Solution

The correct option is A Uphill transport
Facilitated transport is the selective transport of the ions or the molecules through special membrane proteins called as channel proteins. The transport depends on the concentration gradient or the saturation limit. The uphill transport is an example of the active transport in which there is transport opposite to the concentration gradient.
Thus, the correct answer is option A.

Assertion: Both facilitated diffusion and active transport are mediated through membrane proteins.

Reason: Only active transport is selective in action.

Consider the following statements and choose the correct answer.

I. Carrier proteins are needed by both facilitated diffusion and active transport and are sensitive to inhibitors that react with the protein.

II. Different types of proteins present in the membrane play a major role in both active as well as passive transport.

III. The carrier proteins needed by facilitated and active transport are specific.

IV. There is no need of energy to pump molecule against a concentration gradient in active transport.

V. Transport rate reaches the saturation point when all the active proteins are used.
