Transmembrane proteins allow large particles to pass through the membrane.
(a) true
(b) false

True

Explanation:

A trans membrane protein is a type of integral membrane protein that is found on the whole cell membrane.

A trans membrane protein function as the gateway and allows the movement of specific molecules or substance across the membrane.

The larger molecules which cannot travel across membrane is transported with the help of trans membrane proteins.

hence, the given statement is true.
