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.
