What are the main proteins that constitute the sarcomere? What is the function of those molecules in the muscle cells?

4 months ago

In the sarcomere there are organized actin and myosin blocks. Troponin and tropomyosin also appear associated to actin. The actin molecules when activated by calcium ions liberated in the proximities of the sarcomere are pulled by myosin molecules. This interaction between action and myosin shortens the myofibrils originating the phenomenon of muscle contraction.
