An experiment was performed to determine the role that ATP plays in kinesin movement along microtubules. Kinesin and microtubules were incubated together in a test tube, but instead of ATP, a non-hydrolyzable analog of ATP was added to the tube.

What impact on kinesin function do you expect to observe in the presence of this ATP analog?

A. The kinesin would be unable to bind to microtubules since the kinesin would remain inactive.

B. The leading head would bind tightly, but the trailing head would remain free.

C. The kinesin would walk faster along the microtubule since the kinesin would remain active while bound to ATP.

D. The kinesin would bind tightly to microtubules and not release.
