Answer:
ATP hydrolyzation is a process ( catabolic ) whereby chemical energy previously stored in phosphoanhydride bonds will be released by the process of bond splitting
R = Vesicle velocity / step size
Explanation:
The rate of ATP hydrolyzation can be explained  by relating ΔG ( Gibbs free energy)  and Q using this equation :  ΔrGo + RT ln(Q).  where ΔrGo = standard  Gibbs energy change.
while ATP hydrolyzation is a process ( catabolic ) whereby chemical energy previously stored in phosphoanhydride bonds will be released by the process of bond splitting
Calculating R
R = Vesicle velocity / step size
