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 is often incorrectly referred to as creatinine kinase. There are three different forms of creatine kinase that can be measured: CK-MM (located in the skeletal muscles and heart), CK-MB (mainly located in the heart), and CK-BB (located in the brain). An elevated level of creatine kinase, specifically CK-MB, occurs within hours of a heart attack as the heart muscle cells die.
