Answer:

C) They are usually transmembrane

Explanation:

Integral membrane proteins (intrinsic protein) are known to be a type of membrane protein that is attached permanently to the biological membrane. Also, they are made up of significant proteins that are encoded in the genome of the organism. Furthermore, trans-membrane proteins allow the transportation of specific substances across the membrane and they undergo significant changes in order to move substances across or through the membrane.

The correct option is C.

What is integral membrane proteins?

A membrane protein that is permanently connected to the biological membrane is known as an integral membrane protein (IMP).

All transmembrane proteins are not IMPs.

They help in transduction of energy and movement of molecules across cell and organelles.

Thus, the correct option is C, They are typically transmembrane proteins.
