# Average Speed of Kinesin#

Conventional kinesin is a motor protein that moves stepwise along microtubules carrying membrane-bound organelles toward the periphery of cells. It is powered by the hydrolysis of ATP (PubMed, 1999). Assume that the steps of the motion are 8.3 $$nm$$ (the distance between adjacent tubulin binding sites), each step takes about 51.2 $$\mu s$$, and on average there is 14.2 $$ms$$ delay between steps.

## Question Text#
