Where is the major site of body s energy storage quizlet

How does the body store energy?

The body can store some of these fuels in a form that offers muscles an immediate source of energy. 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.

Where is glycogen stored in the body?

Delivering glycogen molecules can to the liver, muscles, and fat cells for storage with plentiful glucose and insulin. Most glycogen is found in the muscles and the liver. The amount of glycogen stored in these cells can vary depending on how active you are, how much energy you burn at rest, and the types of food you eat.

What is the body's stored form of glucose?

Glycogen is the body's stored form of glucose, which is sugar. Glycogen is made from several connected glucose molecules and is your body's primary and preferred source of energy. Glycogen is stored in your liver and muscles and comes from carbohydrates in the foods you eat and drink.

Where is excess glucose stored in the body?

If not, the excess glucose is stored as glycogen in the liver and muscle cells, or as fat in adipose tissue; excess dietary fat is also stored as triglycerides in adipose tissues.

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.

How do humans store fuel reserves?

Because food has not always been readily available, humans (and other animals) have evolved ways to store fuel reserves in their bodies. When food is plentiful, the body packs away extra calories in fat reserves. The stored fat fuels the body when food is scarce.
