ANATOMY

Detailed explanation-1: -Plasma membrane or cell membrane is the outer covering of all cells but it is present below the cell wall in animal cells. It is mainly composed of phospholipid bilayer structure with embedded proteins and some carbohydrates.

Detailed explanation-2: -With few exceptions, cellular membranes-including plasma membranes and internal membranes-are made of glycerophospholipids, molecules composed of glycerol, a phosphate group, and two fatty acid chains. Glycerol is a three-carbon molecule that functions as the backbone of these membrane lipids.

Detailed explanation-3: -So, the correct answer is proteins, carbohydrates, phospholipids.

Detailed explanation-4: -Cell Membrane (Plasma Membrane) The cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable.

Detailed explanation-5: -The principal components of the plasma membrane are lipids (phospholipids and cholesterol), proteins, and carbohydrate groups that are attached to some of the lipids and proteins.
