Let us say that you are working with microtubules. You have attached kinesin (the standard type) dimers to a glass slide and have added complete microtubules to the slide along with ATP. Your kinesins are lined up well enough that you can see the microtobules moving in one direction. Now, suppose to have the two ends labeled so you know which is which. The plus end is oriented to your right and the minus end is to your left. Because the kinesin is fixed, of course, the MT will move in one direction or the other. Which way will it move (to your right or to your left)? Explain
