Explanation of Solution

A sarcomere is a structure in a muscle fiber that consists of half dark and half of light bands. Inside the sarcomere, actin filaments are attached to the proteins of Z-line, but myosin filaments are held at their place because of a protein called titin. Titin is a giant and largest known protein. Titin protein covers myosin molecules and Z-line. Therefore, the titin protein has two functions. It holds the myosin protein, and it is elastic near the Z line; therefore it also helps in the process of stretching.
