Experiment 5. Contraction: In order for the muscle to relax, the actin and tropomyosin union must occur.

Experiment 6. Relaxation: the release of the actin-myosin complex occurs with consumption of ATP, thus it slides and generates contraction, by adding a hydrolyzable analog, this reaction is avoided giving rise to a prolonged actin-myosin binding which leads to relaxation while last effect.

Experiment 7. Ca2 + Contraction is very necessary so that during muscle contraction troponin can be extracted.
