The nutrients stored in body cells and converted into the major fuel source for muscles are primarily carbohydrates, specifically glycogen, and fats. Glycogen is stored in the liver and muscle tissues, while fats are stored in adipose tissue. During physical activity, these nutrients are metabolized to provide energy, with glycogen being the preferred source for high-intensity exercise and fats being used more during prolonged, low-intensity activities.

How does energy get converted from food molecules to muscles?

When we eat food, our body breaks down the molecules through digestion to produce energy in the form of adenosine triphosphate (ATP). Muscles use ATP as a source of energy to contract and carry out their functions. The process by which ATP is produced and utilized in muscles is called cellular respiration.


What energy source is person lifting a chair?

The energy source a person is using when lifting a chair is chemical energy stored in their muscles. When a person contracts their muscles to lift an object, chemical energy from food they have eaten is converted into mechanical energy to perform the task.


What is the relationship between glucose and lactate in the human body?

Glucose is converted into lactate during intense exercise when oxygen supply is limited. This process, called anaerobic glycolysis, helps produce energy quickly. Lactate can be used as a fuel source by muscles and other tissues, and can also be converted back into glucose in the liver.


Where food converted into nutrients?

Plants are the ultimate source of of nutrients and energy.By the process of photosynthesis plants produce 3C compound,which provide carbon backbone for the synthesis of different organic compounds.This carbon backbone is used in the synthesis of vitamins ,proteins and other nutrients.


Why the body need carbohydrate?

The body needs carbohydrates as a source of energy. Carbohydrates are converted into glucose, which is a form of sugar, the body uses to support the function of the muscles and brain.


When you turn on a a radio what is one energy change that happens?

Chemical energy in you body is converted, in you muscles, to mechanical energy which enables you to flip or press the switch.


Where does your body get its chemical energy?

The body gets its chemical energy primarily from the breakdown of nutrients like carbohydrates, fats, and proteins during the process of metabolism. These nutrients are converted into adenosine triphosphate (ATP), which is the main source of energy for cellular processes.


Digestible forms of carbohydrate are converted to what in the body?

Digestible forms of carbohydrates are primarily converted into glucose in the body. This glucose can then be used as a primary source of energy for cells, tissues, and organs. Any excess glucose may be stored as glycogen in the liver and muscles or converted to fat for long-term energy storage.


Glucose is converted to another type of carbohydrate which can be stored?

Glucose is converted into glycogen, a complex carbohydrate, for storage in the liver and muscles. Glycogen serves as a readily available energy source that can be broken down back into glucose when the body needs a quick burst of energy.


Why does the body need carbohydrates?

The body needs carbohydrates as a source of energy. Carbohydrates are converted into glucose, which is a form of sugar, the body uses to support the function of the muscles and brain.


Can lactate be utilized as an energy source in the body?

Yes, lactate can be utilized as an energy source in the body through a process called lactate metabolism, where it is converted into energy in the form of ATP.


What is the brains source of energy?

Glucose is the main source of energy of the brain. It is converted to ATP inside the brain. However, the brain cells (neurons) themselves use some glucose. The other glucose is first metabolized and converted to "Lactate" by cells inside the brain called "Astrocytes". The lactate produced will then enter the neurons and then is converted to ATP.
