Energy System
Cards in this deck (5)
- 1ATP in exercise-Adenosine triphosphate, when broken down gives energy for immediate muscle contractions
-ATP formed when ADP (Adenosine diphosphate binds with another phosphate, when cells need energy it breaks the bond between the phosphate to form ADP and free a phosphate molecule
-Works like a rechargeable battery - 2ATP-PC System-Anaerobic doesn't require oxygen, important for powerful sudden movements
-Lasts for short periods of time (10 secs)
-System occurs between ATP and ADP giving time for the ATP to replenish
-If exercise continues at high intensity, the system will be only partially replenished - 3Lactate systemShort term energy system meets energy requirements for higher intensity exercises for longer periods like 400m race
-Body breaks down carbs into energy resource called glucose which is stored as glycogen - 4Anaerobic glycolysis-ATP-PC begins to fade at around 10 secs, process of anaerobic glycolysis begins
-Breaks down liver and muscle glycogen stores
-Breakdown of glucose and glycogen can be used resynthesise ATP - 5Lactic acid production-Anaerobic glycolysis produces lactic acid as a by-product being a limiting factor to this system
-Accumulates and diffuses into tissue and if not removed it can prevent muscle contraction and cause fatigue
