Detailed explanation-1: -The fundamental building blocks of all cell membranes are phospholipids, which are amphipathic molecules, consisting of two hydrophobic fatty acid chains linked to a phosphate-containing hydrophilic head group (see Figure 2.7).

Detailed explanation-2: -Many macromolecules are made up of smaller molecules called monomers that have been polymerized. Complete answer: The key ingredients of a cell membrane are phospholipids, proteins, and carbohydrate groups which help to form the cell membrane.

Detailed explanation-3: -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-4: -Membrane biogenesis is a process of building the cell membrane by making use of and lipid molecules.

Detailed explanation-5: -So, the correct answer is Lipids.
