Carbohydrate is essential for.. supplying the body with energy

Carbohydrate is essential for:

  • a- building the body
  • b- supplying the body with energy***
  • c- a+b
  • d- none.

The body requires energy to perform its various functions, including movement, breathing, digestion, and temperature regulation. The primary source of this energy is the food we eat, which is converted into a usable form of energy through a complex series of biochemical processes.

The process of converting food into energy is called cellular respiration, and it takes place in the mitochondria, which are the energy-producing organelles found in most cells of the body. During cellular respiration, glucose and other molecules are broken down into a molecule called adenosine triphosphate (ATP), which is the primary currency of energy in the body. ATP is used by cells to fuel various metabolic processes, including muscle contraction and protein synthesis.

In addition to glucose, the body can also use other sources of energy, including fats and proteins. Fats are broken down into fatty acids and glycerol, which can be used by cells to produce ATP. Proteins can also be broken down into amino acids, which can be used as an energy source when glucose and fat stores are depleted.

The body stores excess energy in the form of glycogen in the liver and muscles, which can be quickly broken down into glucose when energy demands increase. In times of prolonged fasting or starvation, the body can also break down muscle tissue to provide energy.

In summary, the body obtains energy from the food we eat through a complex process of cellular respiration, which produces ATP. The body can use a variety of sources for energy, including glucose, fats, and proteins, and it has mechanisms for storing and mobilizing energy as needed.
