17. A researcher wants to determine what controls smooth muscle contractility
Case 1. First, while keeping other factors constant, he added a drug that specifically activated the activities of Rho kinase.
a) what happened to the contractility of the cell? why?
Case 2. To do further testing, he separately added a different reagent that could inhibit the activity of myosin light chain kinase.
b) what happened to the cell contractility this time? why?
