The Energy Systems ATP (Adenosine triphosphate) is produced by almost all living things. They are produced in organelles called mitochondria, which are found in cells. ATP is not energy; rather, it temporarily stores energy in its bonds. When the third phosphate bond is broken, energy is released. This then creates ADP, which has one less phosphate attached to the group. The process of respiration uses two energy systems. Aerobic Respiration, meaning 'with oxygen ', is used for long-term, steady paced exercise and day-to-day activities. Anaerobic Respiration, or 'without oxygen ', produces fast bursts of energy for short, powerful bursts. The Anaerobic system can be divided into two further systems: ATP-PC and Lactic acid. All energy systems work together but the intensity and type of activity will determine which system is predominant. ATP is the usable form of chemical energy for muscular activity. It lasts between 10 and 30 seconds and is stored in most cells, but particularly in muscle cells. The system uses Phosphocreatine (PC) to recreate ATP. There are 3 main different energy systems: the ATP-PC system, the lactic acid system and the aerobic system. The ATP-PC system consists of adenosine triphosphate (ATP) and phosphocreatine (PC). This energy system provides immediate energy through the breakdown of these stored high-energy phosphates. If this energy system is 'fully stocked ' it will provide energy for maximal intensity, short duration exercise for between 10
