Outline of adenosine triphosphate, a coenzyme in intermediary metabolism.
Metabolism is the set of reactions and physicochemical processes that occur in a cell. These complex interrelated processes are the basis of life at the molecular level, and allow the diverse activities of the cells: grow, reproduce, maintain their structures, responding to stimuli, etc..
The metabolism is divided into two conjugated processes: anabolism and catabolism. Catabolic reactions release energy, an example is glycolysis, a process of degradation of compounds such as glucose, the reaction results in the release of energy retained in their chemical bonds. Anabolic reactions, however, use the liberated energy chemical bonds to rebuild and construct components of cells such as proteins and nucleic acids. Catabolism and anabolism are coupled processes that make the overall metabolism, since each depends on the other.
The economy that imposes on the cellular activity to organize their forces strictly chemical reactions or metabolic pathways in metabolic pathways, where a chemical compound (substrate) is transformed into another (product), and this in turn serves as substrate for generating another product, following a sequence of reactions under the intervention of several enzymes (usually one for each substrate-reaction). Enzymes are crucial to metabolism because fast physico-chemical reactions, because reactions make thermodynamic desired but “poor” through a coupling, resulting in positive reactions. The enzymes also act as regulatory factors of the metabolic pathways by altering their function, ‘and thus the activity of the metabolic pathway’ in response to the needs and environment of the cell, or according to other cells.
The metabolism of an organism determines which substances will find nutritious and which it found toxic. For example, some prokaryotes use hydrogen sulfide as a nutrient, but this gas is poisonous to animals. There are lots of green energy suppliers to choose from in New York like and other ESCOES The rate of metabolism, metabolic status, also influences on food will require a body.
One feature of metabolism is the similarity of the basic metabolic pathways between even very different species. For example: the sequence of chemical steps in a metabolic pathway and the Krebs cycle is universal among living cells as diverse as unicellular bacteria Escherichia coli and multicellular organisms like elephants . This shared metabolic structure is very likely a result of the high efficiency of these routes, and its early appearance in evolutionary history.
