Metabolism, also called metabolism (from Greek: μεταβολισμός “metabolismos” = change or transformation), the set of biochemical processes that occur in cells and organisms. Enzymes play central role.

Features of the metabolic
The metabolism has the following features
- The * release of energy from substances listed
- * The use of building materials and energy source for all biological processes
- * The processing of waste
- * The creation and use of reserves.
- * A certain excess building materials eliminate
catabolism and anabolism
Metabolism can be divided into catabolism and anabolism:
* Catabolism is the breakdown of substances, which release energy. This is form of dissimilation or incineration.
* Anabolism is building materials, where energy is recorded. This is form of assimilation.
Major metabolic processes
* Carbohydrates are converted into glucose. This is broken down in glycolysis acetyl-CoA. Glucose can also be converted into other sugars
* Fats are converted into fatty acids. Also fatty acids are degraded to acetyl-CoA in process called beta-oxidation.
* Proteins are degraded to amino acids in the liver. The amino acids can then be used to make new proteins. The amino acid oxidation of amino acids include weather acetyl-CoA formed. Amino acids but can also be converted into many other substances.
* Acetyl-CoA by running the citric acid cycle. These are high-energy electrons and carbon dioxide is produced as waste product.
* The energy rich electrons from the citric acid cycle oxidative phosphorylation. The energy from these electrons is used to generate ATP, the main energy source for the cell.
* Vitamins often play role in various metabolic processes.
Metabolites
Strictly speaking, the metabolites are products of metabolic processes. The term metabolite is normally only used for small molecules such as glucose and amino acids.
There is sometimes distinction made between primary and secondary metabolites. Secondary metabolites are not necessary for the survival of the organism, but do contribute to its survival. Thus, the amino acids from which proteins are built examples of primary metabolites, but the alkaloid nicotine contrast, secondary metabolite of certain plants.
autotrophic and heterotrophic
The metabolism of autotrophic organisms is based on assimilation to remote source, via photosynthesis or chemo synthesis.
The metabolism of heterotrophic organisms is based on energy produced by the decomposition of highly energetic compounds in the environment, many hydrocarbons and other compounds by assimilation in other organisms are made.
Metabolism (Quantity M)
Metabolism is also used in the calculation value technology climate, the heat of human to determine there is greatness in the metabolism created.
The metabolism varies with the activity of person and is expressed in the unit, noting that 1met = 58.2 watts.
With is defined as the heat produced per m2 average person at rest. The average person has an area of 1.8 m2. The average heat production per person is therefore 105Watt.
