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.

well we can't tell you because we cant see the time give a screen shot or something.

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
