Description

The group of chemical processes in organisms that maintain life is known as metabolism. The three primary purposes of metabolism are the conversion of food energy into cellular energy, the breakdown of food into the constituent parts of proteins, lipids, and some carbohydrates, and the disposal of metabolic wastes. Organisms may grow and reproduce, maintain their structures, and react to their environments thanks to these enzyme catalyzed processes. The term metabolism can also refer to the totality of chemical processes that take place within living things, such as digestion and the movement of materials inside and outside of cells. In this case, the set of processes listed above that take place inside cells are referred to as intermediary metabolism. It is possible to characterise metabolic processes as either catabolic by the breakdown of chemicals, such as the conversion of glucose to pyruvate during cellular respiration or anabolic of the creation of compounds are such as proteins, carbohydrates, lipids, and nucleic acids. Typically, anabolism uses energy whereas catabolism releases it.

The chemical processes of metabolism are arranged into metabolic pathways, where one molecule is changed into another by a sequence of stages, each of which is aided by a different enzyme. Because they couple desired energy-consuming activities that organisms want to drive with energy-releasing spontaneous events, enzymes are essential to metabolism. Enzymes function as catalysts, speeding up reactions, and they also allow for the modulation of metabolic reaction rates, for instance in response to environmental changes or messages from other cells. Which compounds an organism will find nourishing and which harmful depends on its metabolic system. For instance, even though hydrogen sulphide is harmful to animals, some prokaryotes use it as nutrition. The quantity of energy used by all of these chemical reactions is measured by an organism's basal metabolic rate. The metabolism of xenobiotics is often divided into three phases are such as modification, conjugation, and excretion. These reactions act in concert to detoxify xenobiotics and remove them from cells.

Conjugation is an only phase II process that takes place in the liver microsomal enzyme system is glutcuronidation, which is also the most frequent one.

Glucuronides are expelled from the body in urine and secreted in bile. As a result, conjugation increases the solubility of most medications, facilitating kidney excretion. Modification is a transcription and other DNA-templated processes are regulated by post-translational changes of histones. Specific modifying enzymes dynamically control this process, and in order to do so, they need metabolites that either act as cosubstrates or as activators or inhibitors of the enzymes' activity.

Excretion is the process through which an organism gets rid of metabolic waste. This is mostly done by the skin, kidneys, and lungs in vertebrates. In contrast, when a material is secreted, it may carry out specified functions after leaving the cell. All types of life require the process of excretion. The synthesis of biomolecules and the production of energy to power important processes are the two primary purposes of metabolism. Endergonic biological substances or chemicals are synthesised by anabolic processes. Your body constantly receives energy from your metabolism for vital processes like breathing and digestion. The basal metabolic rate is the minimal number of calories your body requires to maintain these processes.
