The organism’s need for energy is important to ensure the continuance of its life. To obtain this energy, there is a need to consume quantities of food to then release this energy. There are two ways through them the food compounds can be changed to another form which are anabolism and catabolism. Anabolism is the reactions that construct molecules from small compounds. Catabolism is converting complex molecules into uncomplicated or more simpler units, this process is characterised by the breakdown of chemical bonds in food and the release of energy. Cellular respiration is an example of this process. It requires massive amounts of oxygen and glucose, which come from food, and produces carbon dioxide, water and the energy needed to complete the various vital processes.

Cellular respiration is an important process carried out by all living cells. The word equation for cellular respiration is glucose + oxygen -> carbon dioxide + water. The chemical equation for cellular respiration is ATP (adenosine triphosphate).

“Respiration is the process in all cells of releasing energy from food molecules”. Cellular respiration occurs in the mitochondria, which are the energy storage centre. The shape of the mitochondria helps in the main function of it. The curves in its inner membrane give a large surface area so, the effectiveness in performing its important function. Various factors affect the rate of breathing, including temperature, oxygen and carbon dioxide concentration. As the temperature rises, the rate of cellular respiration increases until it reaches the optimal degree of enzymes. Lack of oxygen reduces the rate of this process. However, when quantities of carbon dioxide are accumulated in the cell, this cause to inhibit the respiratory rate. There are two types of respiration, anaerobic and aerobic.

The process of cellular respiration is very important to all living cells because it provides the energy to do all the necessary functions needed to maintain life. Most cells in our body undergo the process of cellular division to produce two daughter cells. Most single-cell organisms, like bacteria, don’t require much energy so they are able to survive on glycolysis and fermentation.
