Explanation / Answer
CPK stands for creatine phosphokinase. Its an enzyme that catalyzes creatine into phophocreatine by utilizing a molecule of ATP for each reaction. This is reversible reaction and can regenerate ATP molecules when needed by the body mostly in muscle cells, brain cells and heart cells. It basically serves as an energy reservoir as it utilizes ATP when ATP is abundant and saves the the energy of the phosphate bond in phosphocreatine which is brokendown reversibly to reproduce ATP when ATPs are deficient in body.
An elevated CPK level indicates
heart attack- myocardial infarction.
Excessive muscle break down-rhabdomylysis
Kidney injury, muscle disorder
