Solution

Movement of substances against concentration gradient is called active transport. Here ions are moving opposite their electro-chemical gradient.So it is called active transport.

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 (A): Active transport is uphill transport.

Reason (R): Active transport uses energy to pump molecules against the concentration gradient.
