Detailed explanation-1: -Carbohydrate Chains, or glycolipids/glycoproteins, are chains found on the surface of the cell membrane that are made of carbohydrates + lipid (or) protein. The primary function of these chains is to recognize harmful cells (cell-cell recognition).

Detailed explanation-2: -Carbohydrates on the cell membrane help cells function properly. Carbohydrates do this in two ways: helping cells recognize each other and providing protection for cells.

Detailed explanation-3: -The primary function of carbohydrates is to provide energy for the body, especially the brain and the nervous system.

Detailed explanation-4: -The cell membrane, therefore, has two functions: first, to be a barrier keeping the constituents of the cell in and unwanted substances out and, second, to be a gate allowing transport into the cell of essential nutrients and movement from the cell of waste products.

Detailed explanation-5: -Carbohydrate groups are present only on the outer surface of the plasma membrane and are attached to proteins, forming glycoproteins, or lipids, forming glycolipids.
