Upon further analysis of the mode of action of Chemical Z, you notice that there was a significant rise in the levels of calcium ions in the sarcoplasm of the smooth muscle.
Skeletal and cardiac muscles are still able to contract. Based on this new information, please choose the BEST answer from the statements below!
1. Poison Z caused the above effects by inhibiting the electrical signal going down the T-tubules
2. Poison Z prevented calcium from binding to myosin light chain kinase
3. Poison Z prevented myosin from binding to actin
4. Poison Z prevented the movement of tropomyosin off the myosin binding sites
5. Poison Z prevented the binding of calcium to troponin
6. Poison Z destroyed the dense bodies
7. Poison Z prevented the release of calcium from the SR
8. Poison Z prevented myosin light chain kinase from phosphorylating myosin
9. Poison Z destroyed intermediate filaments
