Which biomolecule is useful for insulation and energy storage in the human body?
A
Carbohydrates
B
Lipids
C
Nucleic Acids
D
Proteins
Explanation: 

Detailed explanation-1: -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. A fat is made up of a glycerol, which is attached to 1 to 3 fatty acid chains.

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 main biological functions of lipids include storing energy, as lipids may be broken down to yield large amounts of energy. Lipids also form the structural components of cell membranes, and form various messengers and signaling molecules within the body.

Detailed explanation-4: -They are used in the production of cell membranes and hormones, as well for maintaining vision and supporting the immune system. These lipids provide structure and support for the walls of every cell in your body. Communication between cells is also dependent upon lipids in your cells’ membranes.

Detailed explanation-5: -Lipids also provide insulation from the environment for plants and animals. For example, they help keep aquatic birds and mammals dry because of their water-repelling nature. Lipids are also the building blocks of many hormones and are an important constituent of the plasma membrane.
