Creatine Phosphate also called as creatine is a source of energy which on reaching the muscle is converted into phosphocreatine. It provides energy during heavy work out when there are depleted levels of ATP and acts as a major source of energy.
5. During short bursts of extreme muscular activity, lactate (lactic acid) can build up to high concentrations in the muscles and blood. the reason usually given to explain this accumulation is during strenuous work out sessions the oxygen present in the blood cannot produce energy that can satisfy the demand of the body so, there are other processes that start functioning in the body that operate in the absence of oxygen to produce ATP for which lactic acid is the end product. During exercise the energy stores in the muscle are depleted and the energy is derived from other process which are biochemical and metabolic in nature. They tend to release substances like lactate which accumulate and lead to generation of muscle fatigue because the muscle cannot excrete the metabolites compared to the speed at which they are produced.
6. Mitochondria are an essential part of the cell structure which is responsible for generation of energy. Mitochondria Cytopathy is a disease that affects the mitochondria leads to decrease in production of energy leading to multiple organ failure.
