Understanding Respiration


Respiration in biology is the process of mobilization of energy the body living through solving high-energy compounds (SET) to be used in carrying out the functions of life. In terms of activities of daily living, respiration can be likened to breathing. However, the term includes the processes of respiration are also not covered by the terms of breathing. Respiration occurs at all levels of living organisms, ranging from individuals to the smallest unit, the cell. If breathing is usually associated with the use of oxygen as a compound splitter, not only involving oxygen respiration.

Basically, respiration is the process of oxidation experienced by SET as chemical energy storage unit in the living organism. SET, such as sugar molecules or fatty acids, can be broken with the help of enzymes and some simple molecules. Since this process is an exothermic reaction (releasing energy), the energy released was captured by ADP or ATP or NADP to form NADPH. In turn, various biochemical reactions endothermic (requires energy) supplied its energy needs from the last two groups of compounds.

Most of which can be witnessed human respiration requires oxygen as oksidatornya. Such a reaction is called aerobic respiration. However, many processes that do not involve oxygen respiration, called anaerobic respiration. The most commonly known one is in the process of making alcohol by the yeast Saccharomyces cerevisiae. Various anaerobic bacteria use sulfur (or compounds) or some metal as an oxidant. Respiration performed on the unit cell. The process of respiration in eukaryotic organisms occurs in the mitochondria.
