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#
