The organism's need for energy is important to ensure the continuation of its life. To obtain this energy it is necessary to consume quantities of food and then release this energy. There are two ways in which food compounds can be changed into another form which are anabolism and catabolism. Anabolism is the reactions that build molecules from small compounds. Catabolism consists of the conversion of complex molecules into simple or simpler units, this process is characterized by the breaking of chemical bonds in foods and the release of energy. Cellular respiration is an example of this process. It requires enormous quantities of oxygen and glucose, which come from food, and produces carbon dioxide, water and the energy necessary to complete various life processes. Say no to plagiarism.

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 center. The shape of the mitochondria helps its main function. The curves in its internal membrane give it a large surface area, therefore effectiveness in carrying out its important function. Various factors influence breathing rate, including temperature, oxygen and carbon dioxide concentrations. As the temperature increases, the rate of cellular respiration increases until the optimal level of enzymes is reached. Lack of oxygen reduces the speed of this process. However, when quantities of carbon dioxide accumulate in the cell, this causes the respiratory rate to be inhibited. There are two types of respiration, anaerobic and aerobic. Please note: this is just an example. Get a custom paper from our expert writers now. Get a Custom Essay The process of cellular respiration is very important for all living cells because it provides the energy to perform all the necessary functions needed to maintain life. Most cells in our body undergo the process of cell division to produce two daughter cells. Most single-celled organisms, such as bacteria, do not require much energy, so they are able to survive through glycolysis and fermentation.
