(a) true
(b) false

The given statement is true.

Explanation:

A channel protein refers to a protein, which permits the conduction of particular substances like small molecules or ions through the cell membrane. They perform this task either through the process of active transport or facilitated diffusion on the basis of the concentration gradient or due to the variation in the concentration of components outside and within the cell membrane.
