Chapter 10.10, Problem 34WDYL

Summary Introduction

To explain:

The specific role of the following structure within smooth muscle cells: calmodulin, myosin light-chain kinase, and myosin light-chain phosphatase.

Concept introduction:

The thin filaments of smooth muscles are composed of tropomyosin and actin but do not contain troponin molecules as present in the skeletal muscle fibers. Instead, smooth muscles contain other proteins for the initiation of contraction.
