Solution

The correct option is D (1) and (3) both
In facilitated diffusion ,special proteins help move substances across membranes without expenditure of ATP energy. While in case of Active transport it uses energy to pump molecules against a concentration gradient .
In both case , transportation rate reaches a maximum when all of the protein transporters are being used (saturation).
So the correct option is 'One and three both' .

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.

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

Reason: Only active transport is selective in action.
