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.
The creatine kinase test measures the blood levels of certain muscle and brain enzyme proteins. Creatine kinase (CK or CPK) is an enzyme (a type of protein) found in muscle and brain.Normally, very little CK is found circulating in the blood. Elevated levels indicate damage to either muscle or brain; possibly from a myocardial infarction (heart attack), muscle disease, or stroke.reatine kinase (CK or CPK) is an enzyme (a type of protein) found in muscle and brain.
