Sarcomere Lab Report

I am a parasitic bacteria that has evolved sharp edges around it that can cut up proteins, specifically titin filaments found in the sarcomere. I would infect the sarcomeres through the T-tubules found on the sarcolemma and start detecting for titin filaments. As it is attached to the Z Disc and the myosin heads, I would start making my way there to destroy them. Once I have found the titin filaments, I would bind to them and thus cut up the protein. Titin filaments are important as they hold the sarcomere together when the myosin heads of the thick filaments are not attached to the thin filaments. They connect the Z Disc to the M line in the sarcomere and contribute to the contraction of striated muscle tissues by force transmission at the Z Disc and resting tension of the I band region. Without titin filaments, the range of motion of the sarcomere in tension would not be limited and our muscle would then lose its passive stiffness. This would disable the proper function of the human muscular system.
They function as a molecular spring and are responsible for the passive elasticity of our muscles. They are made out of 244 individually folded protein domains and are connected by unstructured peptide sequences. When there is tension, the domains will unfold and allow the protein to be stretched. When tension is released, the domains will then fold back again. By keeping the myosin heads of the thick filaments in place, it allows the sarcomere to function like usual and muscle contraction can take place as
