The study of a living being is called biology.

The correct answer is A.

The integral membrane protein is the protein that has a hydrophobic chain that interacts with the fatty acid group of the Phospholipids membrane that helps it to attach to biological molecules. This integral membrane protein is present inside the membrane.

The functions of Integral proteins are as follows:-

Examples are insulins receptors, integrin, selection, etc.

Hence, the correct answer is A that is All of these require integral proteins.

Option A.

All of these require integral protein.

Explanation:

Integral membrane protein is the protein that have hydrphobic chain which interact with fatty acid group of the Phospholipids membrane that help it to attach to biological molecules.

Integral proteins functions as transporters, linkers, receptors,channels of potassium and sodium, help to accumulate energy, proteins pump. Examples are insulins receptors, integrin, selectins e .t.c
