What Are The Three Sources Of Energy Your Body Uses In Order

The aerobic energy system is where we utilize all 3 of our fuel resources.

What are the three sources of energy your body uses in order.

The body uses 3 different systems to supply cells with the necessary atp to fuel energy needs. Most notably sugars and fats are used by the body as energy sources. Atp pc anaerobic glycolysis and aerobic phosphorylation. Atp which stands for adenosine triphosphate is the sole source of energy for all human metabolism yet very little of this fuel is actually stored in the body.

Carbohydrate fat and protein. The body uses carbohydrate fat and protein to provide necessary energy to sustain cellular activities both at rest and during exercise 3. This energy takes three forms. Carbohydrates such as sugar and starch for example are readily broken down into glucose the body s principal energy source.

Within these cells and from these energy sources adenosine triphosphate atp is formed to provide fuel. However these micronutrients are required in smaller. Your atp pcr system is involved in short term anaerobic energy. As exercise intensity.

Energy in the human body comes from the food we eat. Your glycolytic system produces energy through the breakdown of carbohydrates stored in your muscles and liver. The utilization of fat carbs during exercise. Our bodies require other nutrients too like essential vitamins and minerals.

Macro means large and these basic nutrients are necessary in large quantities to sustain our growth metabolism and other bodily functions. Carbohydrates come through the glycolytic system creating pyruvate that continues right into the aerobic system. The energy or calories in the food we eat comes from three macronutrients. In circumstances such as starvation the body will begin to break down.

Most of the body s activities use a continuum of all three energy systems working together to ensure a constant supply of energy. Each system uses different starting fuels each provides atp at different. Fats are metabolized more slowly than carbs and are the preferred energy source during long duration low intensity exercise such as walking. See table 2 1 estimated energy stores in humans the body can store some of these fuels in a form that offers muscles an immediate source of energy.

Instead the body has three different systems of atp production. It is within this system that carbohydrates fats and proteins may be refined in order to create atp. Your body operates off of three main energy systems. The aerobic energy system.

Proteins fats and carbohydrates. The regulation of fuel selection during exercise is under complex control and depends on several factors including diet as well as intensity and duration of exercise 3. Essential nutrients are compounds the body can t make on its own or in enough quantity.
