Phosphatase correct answers This myosin-actin interaction forms the basis of the cross-bridge cycle (CBC), which causes muscle contraction, as in skeletal -bridge cycling (CBC) requires phosphorylation of the myosin light chain (LC20). A .............. is an enzyme that removes a phosphate group from its substrate composed of actin and are dynamic and are lengthen by polymerization or shortened by depolarization correct answers microfilaments are provide strucule support for the cell ...
