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 ...

What does the term force describe? correct answers an outside influence on an object. What is a frame of reference? correct answers means that if the placement of one object is known, it is easier to locate another object with respect to the position of the original object. What is speed a measurement of? correct answers an objects movement or change in position (x), over a change in time (t). What is the measurement of speed with direction called? correct answers velocity What is th...
