Question

which cpk isoenzyme is indication for muscle damage? cpk-mm cpk-mb cpk-bb

Explanation:

CPK (creatine phosphokinase) has different isoenzymes. CPK - MM is mainly found in skeletal muscle. When there is muscle damage, CPK - MM is released into the bloodstream. CPK - MB is more associated with heart muscle (cardiac muscle) damage (though it can also be elevated in some skeletal muscle disorders to a lesser extent compared to CPK - MM in pure skeletal muscle damage). CPK - BB is found in the brain and smooth muscle.

Answer:

CPK - MM
