  • ATP - Biology-Online Dictionary
    0 9 OTHER View View source History ATP Definition noun biochemistry 1 Abbreviation for adenosine triphosphate empirical formula C 10 H 16 N 5 O 13 P 3 2 An organic compound composed of adenosine an adenine ring and a ribose sugar and three phosphate groups hence the name Supplement ATP is a nucleotide that contains a large amount of chemical energy stored in its high energy phosphate bonds It releases energy when it is broken down hydrolyzed into ADP or Adenosine Diphosphate The energy is used for many metabolic processes Hence ATP is considered as the universal energy currency for metabolism ATP is produced via cellular respiration in the mitochondria and photosynthesis in chloroplasts Its functions are for intracellular energy transport for various metabolic processes including biosynthetic reactions motility and cell division It is also used as a substrate by kinases that phosphorylate proteins and lipids and by adenylate cyclase to produce cyclic AMP Word origin from abbreviation of adenosine triphosphate Compare AMP ADP See also cellular respiration Retrieved from http www biology online org bodict index php title ATP oldid 97733 First Previous ANS Next ATP Production Last Please contribute to this project if you have more information

  • ATP synthase - Biology-Online Dictionary
    ATP synthases An enzyme that catalyzes the formation of ATP from the phosphorylation of ADP with inorganic phosphate using a form of energy such as the energy from a proton gradient Supplement This enzyme consists of two major segments F o portion the transmembrane proton channel and F 1 portion the catalytic component The proton channel component allows the diffusion of protons hydrogen ions from an area where there are more hydrogen ions to an area where there are less hydrogen ions due to a proton gradient As the proton H ion moves down the concentration gradient this moves the enzyme in a spinning motion which brings ADP and inorganic phosphate together to form a bond thus creating ATP molecule The resulting ATP molecule is released so that a new ADP molecule can enter for another phosphorylation This enzyme can also work in reverse using the energy release from ATP hydrolysis to pump protons against their thermodynamic gradient Since it can also use ATP as a source of energy it is also aptly called ATP synthetase See also chemiosmosis Retrieved from http www biology online org bodict index php title ATP synthase oldid 96411 First Previous ATP Production Next ATP

  • ATP synthetase - Biology-Online Dictionary
    portion the catalytic component The proton channel component allows the diffusion of protons hydrogen ions from an area where there are more hydrogen ions to an area where there are less hydrogen ions due to a proton gradient As the proton H ion moves down the concentration gradient this moves the enzyme in a spinning motion which brings ADP and inorganic phosphate together to form a bond thus creating ATP

  • ATPase - Biology-Online Dictionary
    ATP into ADP and a free phosphate ion thereby releasing energy for use in another biochemical reaction Supplement Examples of ATPases are transmembrane ATPases that move solutes across the membrane especially against their concentration gradient and V ATPases that are primarily found in eukaryotic vacuoles catalysing ATP hydrolysis to transport solutes and lower pH in organelles See also ATP synthase Retrieved from http www biology online org bodict index php
