Detailed explanation-1: -So, the correct answer is Lipids.

Detailed explanation-2: -Triglyceride is the most common lipid that is used for energy storage.

Detailed explanation-3: -Lipid-A type of organic molecule which is non-polar. Lipids are polymers; the monomers which make them up are usually fatty acids. They are important energy storage molecules, structural molecules, and hormones.

Detailed explanation-4: -Glycogen is a polysaccharide made by animals for energy storage. If it is not used, then it will be converted to fat for more permanent storage. Starch is a polysaccharide that functions as plant storage. The polysaccharide cellulose provides structure to plants.

Detailed explanation-5: -Lipids have four main types of polymers: triglycerides, phospholipids, waxes, and steroids. Triglycerides are made of a glycerol backbone and three fatty acid tails that differ in length and orientation. Triglycerides with single-bonded carbons are called saturated fats.
