1. What are three ways in which vesicles in a cell are movedusing directed motion.
2. What is the average size of a myosin motor step along anactin filament in nm)? What is the average size of a kinesin motorstep along / (across) a tubulin dimer (in nm)?
3. Write the definition of the rate of ATP hydrolyzation Rinyour own words. How would you calculate the rate of ATPhydrolyzation, you know the step size of the motor proteins and theaverage vesicle velocity. Write the equation here.
4.Use the equation from Question 3 and your answer to Question 2to calculate the rate of ATP hydrolyzation, R. For step size,assume the vesicle is being transported by a myosin motor protein.(Hint: make sure you convert values to the appropriate units) Theunits for rate of ATP hydrolysis are s-1
