ABSTRACT
A definition of the term "troponin" is presented. It refers to an inhibitory protein in muscle fibers. The kind of action potential at the sarcolemma causes the sarcoplasmic reticulum to release calcium ions while creating bond to troponin. It shifts tropomyosin away from the myosin binding sites of actin and permits contraction.
