Introduction:
Cell is also known as chemical factory which help in breakdown of molecules (organic) for the production of the energy. The cell uses this energy for the synthesis of ATP (energy form). Mitochondria are the organelle present in the cells where most energy synthesizing reactions takes place. So cell depends on the supply of the nutrients and oxygen.
Explanation of Solution
Oxygen is absorbed by the lung and the other substances like vitamins, minerals, fat, proteins and carbohydrates are absorbed by the process of digestion. The circulatory system (cardiovascular system) helps in transport of these materials to the different part of the body. They diffuse into tissue from the blood and absorbed by the cells.
Mitochondria present inside the cell breaks down these materials (organic nutrient) to provide energy for cell division, cell growth, secretions, contraction and other body function. All these
The chemical reactions that take place inside the cell are known as “cellular metabolism”
