Question

which of the creatinine phosphokinase isoenzymes are increased with muscle injury?

Explanation:

Creatine phosphokinase - MB (CK - MB) and CK - MM are the isoenzymes that increase with muscle injury. CK - MM is the predominant isoenzyme in skeletal muscle and its levels rise significantly in muscle - related damage. CK - MB is also elevated in cases of muscle injury, especially in cardiac - related muscle damage but can also be present in skeletal muscle injury.
