Respiration |

Respiration is a process in which glucose is broken down into simpler chemicals the energy. This energy is then released so that cells can use it for things such as movement, warmth and growth of an organism. Thus to maximize the energy out of glucose it is usually best to react it with oxygen to produce carbon dioxide and water. This is called Aerobic respiration. In scientific terms, Aerobic respiration is viewed to be: Glucose + Oxygen => Carbon dioxide + Water + released energy It must be understood however that it is possible for organism's cells to respire without any oxygen. For example, you are running at a faster pace, there is little room for the body to get enough oxygen to all of the muscles. Thus, in this case the cells do anaerobic respiration, which is defined to be respiration without oxygen. The glucose released is turned into lactic acid, resulting in a small amount of energy. However, lactic acid is harmful for the body, thus such a form of respiration is not good for an extended period of time. Thus almost every living thing is characterized by respiration; their cells have to respire for such organisms to live. |
