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 also known as CPK or Creatine phosphokinase is an enzyme that is found in the brain, heart, and skeletal muscles. This enzyme encourages a particular biochemical reaction to occur. CK normally adds phosphate to creatine present in our body and turns it into molecule phosphocreatine which is high-energy.
