Detailed explanation-1: -Fats (lipids) Fats are the primary long-term energy storage molecules of the body. Fats are very compact and light weight, so they are an efficient way to store excess energy.

Detailed explanation-2: -Lipids perform many different functions in a cell. Cells store energy for long-term use in the form of lipids called fats. Lipids also provide insulation from the environment for plants and animals.

Detailed explanation-3: -The amount of energy stored as lipids is greater than the amount stored as glycogen since the human body cannot store as much glycogen as lipids can.

Detailed explanation-4: -Fats are used to store energy within their chemical bonds. They also serve as insulation in organisms that maintain a constant body temperature, such as mammals and birds. The building blocks of fats are triacylglycerol molecules. These molecules are composed of one glycerol and three fatty acids.
