Detailed explanation-1: -Dietary carbohydrates provide glucose that body cells can use for energy. Excess glucose beyond what the body needs for immediate energy is converted into glycogen, a storage form of carbohydrate, or converted into fat and stored in body fat cells. Glucose provides energy for all body cells.

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: -Plants store carbohydrates in long polysaccharides chains called starch, while animals store carbohydrates as the molecule glycogen. These large polysaccharides contain many chemical bonds and therefore store a lot of chemical energy.

Detailed explanation-4: -Glucose, or blood sugar, is the main source of energy for your body’s cells, tissues, and organs. Glucose can be used immediately or stored in the liver and muscles for later use.

Detailed explanation-5: -Cells store sugar molecules as glycogen in animals and starch in plants; both plants and animals also use fats extensively as a food store.
