WebThe interaction of myosin and actin proteins be at the core of our current understanding of sarcomere shortening. How does this shortening happen? It has something to perform with a sliding interaction amidst actin both myosin. Figure 1: A gastrocnemius mask (calf) with striped pattern of sarcomeres. WebPossible exam wording: Frog skeletal muscle consists of thick filaments that are about 1.6 μ m long and thin filaments that are about 1 μ m long. a) Imagine that the sarcomere has a resting length of 3.2 μ m. Calculate the length of the A-band, I-band, and H-zone (the region of the thick filaments that does not overlap with the thin filaments) for this sarcomere.
