Glycolysis As omnivores we consume plants and animals which provide us with macro-nutrients - lipid, carbohydrates (CHOs) and proteins. These can all be utilised for adenosine tri-phosphate (ATP). Then one of the ATPs high-energy phosphate bonds is broken resulting in one adenosine diphospate (ADP) molecule, one inorganic phosphate and 7.3 Kcal of energy (S.Luciano A. Vander J.Sherman 1978). There are 3 energy systems which give us ATP - the creatine phosphate system (PCr), anaerobic glycolysis and the aerobic system. All three systems work to varying degrees depending on the intensity of exercise. The majority of the 1500m race will be 60% aerobic (Beashel and Taylor 1996). During the last 200m of the race the primary energy system is anaerobic glycolysis. This system is much less efficient producing 2 moles of ATP for 1 glucose molecule, compared with the aerobic system which produces 36-38 moles of ATP. However, glycolysis is...
