How are energy substances stored?

Storage and utilization of energy substances involve two different controlling processes. In advanced animals, glucose is stored in the form of hepatic and muscle glycogen, and glycogen is re-used by phosphorolysis. Fatty acids are stored in the form of fat, especially hypodermic fat, and provide energy to the body through β-oxidation.

How is energy stored in the body?

Energy is stored in the form of fat, and meets the demand of body via two coupled mechanisms: catabolism and oxidative phosphorylation. Under normal physiological conditions, fat consumption involves ketone body metabolism through the circulatory system and glucose consumption requires blood lactic acid cycle.

How is energy stored in human beings in the form of fat?

In other words, the energy stored in human beings in the form of fat can only be decomposed through energy consumption and circulated in the form of ketone bodies. The major component of ketone bodies is β-hydroxybutyrate (β-OHB), which is an energy molecule from fat and is circulated in animals in vivo.

How energy is locally stored and used?

This leads us to a discussion about how energy is locally stored and used. Catabolism. ATP, adenosine triphosphate (a-duh’-nuh-seen), is the basic unit of energy storage in the body and it enables the rapid release of energy. Why does the body convert food fuel to ATP and not directly oxidize carbohydrates, fatty acids, and proteins?

What happens if energy substances exceed storage capacity?

When energy substances exceed storage capacity, the body initiates an “alarm signal”, eliminates accumulated energy directly by improving catabolism or in the form of blood or urine glucose, promotes cell proliferation, produces excessive immunity, and even causes cancer. These processes are controlled by mTOR nutrient-sensing system.

Where are surplus energy substances stored?

Therefore, surplus energy substances such as fats, carbohydrates, or proteins are usually stored in adipose tissues. Removal of excess fat is essential for better survival. The most important system in advanced animals is the immune defense system.
