Food and water
The preferred fuel source for the body is glucose.
Carbohydrates are the main source of energy for the human body. When consumed, they are broken down into glucose, which is used by the body’s cells as fuel to carry out various functions. Other sources of energy include fats and proteins, but carbohydrates are the body’s preferred and most efficient source of energy.
No, proteins are not the main source of energy in the human body. Carbohydrates and fats are the primary sources of energy, while proteins are mainly used for building and repairing tissues.
The main fuel source for the work of the cell is the mitochondria.
The main source of energy for the body comes from glucose, which is derived from carbohydrates in the diet. Glucose is utilized by cells for various functions and is the primary fuel for metabolic processes in the body.

The human body's main source of energy comes from carbohydrates, which are broken down into glucose through digestion. Glucose is then used by cells for energy production through a process called cellular respiration.
Carbohydrates are considered an energy source for the human body as they are broken down into glucose for fuel. They also serve as building blocks for structures such as cell walls and DNA, providing essential components for growth and repair processes.
During early starvation, the body primarily uses glycogen stores from the liver and muscles as a fuel source. Once these stores are depleted, the body shifts to using fatty acids from adipose tissue as its main source of energy.
The body can utilize protein, carbohydrates and fat for fuel.
coal was the main source at that time
