1. Using the blank diagram of a sarcomere label the parts, then describe the sliding filament model of muscle contraction, stating how the following zones change as a result of muscle contraction: I band, A band, H zone, the distance between Z lines. Also include the role of ATP, Ca2+, troponin, & tropomyosin
