2. Explain the relationship between the following three terms: actin, myosin, striations.

Explanation:

The regulation of actin-myosin contraction in striated muscle, discussed earlier, is mediated by the binding of Ca2+ to troponin. In nonmuscle cells and in smooth muscle, however, contraction is regulated primarily by phosphorylation of one of the myosin light chains, called the regulatory light chain (Figure 11.28).
