Adenosine triphosphate (ATP) is a nucleoside triphosphate [2] that provides energy to drive and support many processes in living cells, such as muscle contraction, ...
ATP is the only type of usable form of chemical energy for musculoskeletal activity. It is stored in most cells, particularly in muscle cells. Other forms of chemical energy, such as those available from oxygen and food, must be transformed into ATP before they can be utilized by the muscle cells.
The Association of Tennis Professionals (ATP) is the governing body of the men's professional tennis circuits – the ATP Tour and the ATP Challenger Tour.It was formed in September 1972 by Donald Dell, Jack Kramer, and Cliff Drysdale to protect the interests of professional tennis players, and Drysdale became the first president.
This process is an important component of all vertebrates' bioenergetic systems. For instance, while the human body only produces 250 g of ATP daily, it recycles its entire body weight in ATP each day through creatine phosphate. Phosphocreatine can be broken down into creatinine, which is then excreted in the urine. A 70 kg man contains around ...
ATP + Creatine → ADP + CP + H + (Mg 2+ assisted, catalyzed by creatine kinase) ADP + P i → ATP (during anaerobic glycolysis and oxidative phosphorylation ) When the Phosphagen System has been depleted of phosphocreatine (creatine phosphate), the resulting AMP produced from the adenylate kinase (myokinase) reaction is primarily regulated by ...
If you see this term in a text, there are a couple of possible meanings.
The adenylate energy charge is an index used to measure the energy status of biological cells.. ATP or Mg-ATP is the principal molecule for storing and transferring energy in the cell : it is used for biosynthetic pathways, maintenance of transmembrane gradients, movement, cell division, etc...
The phosphogenic (ATP-PC) anaerobic energy pathway restores ATP after its breakdown via creatine phosphate stored in skeletal muscle. This pathway is anaerobic because it does not require oxygen to synthesize or use ATP. ATP restoration only lasts for approximately the first 30 seconds of exercise. [3]
