Body s main storage form of energy

What is the main energy source in the body?

Carbohydrates, such as sugar and starch, for example, are readily broken down into glucose, the body's principal energy source. Glucose can be used immediately as fuel, or can be sent to the liver and muscles and stored as glycogen. During exercise, muscle glycogen is converted back into glucose, which only the muscle fibers can use as fuel.

What is the storage form of a complex carbohydrate?

The storage form of a complex carbohydrate composed of multiple units of glucose linked together in a highly branched structure. The molecules from which proteins are built, each protein being composed of a specific sequence of linked amino acids.

What is the body's stored form of glucose?

Does your body have enough energy?

Most of us have sufficient energy stores of fat (adipose tissue or body fat), plus the body readily converts and stores excess calories from any source (fat, carbohydrate, or protein) as body fat. In order for fat to fuel exercise, however, sufficient oxygen must be simultaneously consumed.
