NEET BIOLOGY

Detailed explanation-1: -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-2: -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-3: -One type of lipid, the triglycerides, is sequestered as fat in adipose cells, which serve as the energy-storage depot for organisms and also provide thermal insulation.

Detailed explanation-4: -Triglyceride is the most common lipid that is used for energy storage. Triglycerides are the main body fat constituents for vertebrates. They are tri-esters comprising a glycerol molecule that is bound to three fatty acid molecules. The unused calories of our body are stored in the form of triglycerides.

Detailed explanation-5: -Lipids in the blood are absorbed by liver cells to provide energy for cellular functions. The liver is responsible for providing the proper concentrations of lipids in the blood. Some lipids are utilized by brain cells to synthesize brain and nerve tissue.
