BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Lipids (phospholipids and cholesterol), fats, and carbohydrate groups bound to each of the lipids and proteins are the main components of the plasma membrane. Glycerol, two fatty acid tails, and a phosphate-linked head group make up a phospholipid.

Detailed explanation-2: -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-3: -Cell membranes are composed of proteins and lipids.

Detailed explanation-4: -Like all other cellular membranes, the plasma membrane consists of both lipids and proteins. The fundamental structure of the membrane is the phospholipid bilayer, which forms a stable barrier between two aqueous compartments.

Detailed explanation-5: -Phospholipids consist of a glycerol molecule, two fatty acids, and a phosphate group that is modified by an alcohol.
