Photosynthesis is the process used by plants, algae and certain bacteria to harness energy from sunlight and turn it into chemical energy.
In some cases the test may be used to detect muscle conditions such as polymyositis (condition characterized by the inflammation of muscles) or to estimate the degree of muscle damage. Stroke and other forms of brain damage can also result in an elevated creatine kinase level.
Creatine kinase, more commonly known as CK, is an enzyme that is present in all muscle tissue of the body including the heart and the brain. The normal creatine kinase levels in a man are between 38 and 174 units/L; while a woman's creatine kinase levels range from between 96 to 140 units/L.erum creatine levels indicate the overall health of the muscles within the body and if a serum creatine kinase test shows elevated levels, this is an indicator of strain on the muscles that may have been caused by simply heavy exercise or even something as serious as a heart attack.
