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 (CK) is an enzyme found in the heart, brain, and skeletal muscle. High amounts of CK are released into the blood when there is muscle damage. A CK blood test may be used to detect inflammation of muscles (myositis) or muscle damage due to muscle disorders (myopathies).
