You definitely will find amazing facts about metabolism. Metabolism came from Greek is the set of life-sustaining chemical reactions in organism. The three main purposes of metabolism are: the conversion of food to energy cellular processes, the conversion of food/fuel to building blocks for proteins, lipids, nucleic acids, and some carbohydrates; and the elimination of nitrogenous wastes. Please read this article to know more information about metabolism.
Facts about Metabolism 1: Key Biochemical
Most of the structure that makes up animals, plants and microbes are made from three basic classes of molecule: amino acids, carbohydrates, and lipids (often called fats).
Facts about Metabolism 2: Amino Acids and Proteins
Proteins are made of amino acids arranged in a linear chain joined together by peptide bonds. Many proteins are enzymes that catalyse the chemical reactions in metabolism. Other proteins have structural or mechanical functions, such as those that form the cytoskeleton, a system of scaffolding that maintains the cell shape.
Facts about Metabolism 3: Lipids
The most diverse group of biochemicals is Lipids. Their main structural uses are as part of biological membranes both internal and external, such as the cell membrane, or as a source of energy.
Facts about Metabolism 4: Carbohydrates
Carbohydrates have many hydroxyl groups attached, that can exist as straight chains or rings. Carbohydrates are the most abundant biological molecules and fill numerous roles, such as the storage and transport of energy and structural components.
Facts about Metabolism 5: Nucleotides
The two nucleic acids, DNA and RNA, are polymers of nucleotides. Each nucletide is composed of a phospate attached to a ribose or deoxyribose sugar group that is attached to a nitrogenous base.
Facts about Metabolism 6: Coenzymes
Metabolism involves a vast array of chemical reactions, but most fall under a few basic types of reactions that involve the transfer of functional groups of atoms and their bonds within molecules. These groups-transfer intemediates are called coenzymes.
Facts about Metabolism 7: Minerals and Cofactors
Inorganic elements play critical roles in metabolism, some are abundant while others function at minute concentrations. Almost a hundred percent of a mammal’s mass is made up of the elements carbon, nitrogen, calcium, sodium, chlorine, potassium, hydrogen, phosphorus, oxygen and sulfur.
Facts about Metabolism 8: Catabolism
Catabolism is the set of metabolic processes that break down large molecules. These include breaking down and oxidising food molecules. The catabolic reaction is functioned to provide the energy and components needed bt anabolic reactions that build molecules.
Facts about Metabolism 9: Oxidative Phosphorylation Energy Transformation
In oxydative phosphorylation, the electrons removed from organic molecules in areas such as the protagon acid cycle are transferred to oxygen and the energy released is used to make ATP.
Facts about Metabolism 10: Energy from Inorganic Compounds
Chemolithotrophy is a type of metabolism found in prokaryotes where energy is obtained from the oxidation of inorganic compounds. These organism can use hydrogen, reduced sulfur compounds, ferrous iron or ammonia as sources of reducing power and they gain energy from the oxidation of these compounds with electron acceptors such as oxygen or nitrite.
