So we see that there are several important differences between eukaryotic and prokaryotic flagellum. So there are differences in not only structure and composition, but also the source of energy as well as the type of motion that is made by our flagella. So let's look at the following table that basically summarizes the most important differences between prokaryotic and eukaryotic flagella. So there is a difference in motion. For eukaryotic, we have our dynamic proteins that basically use our ATP energy source to slide along our microtubules, creating a bendinglike motion. So for eukaryotic case, we have a bendinglike motion, for our prokaryotic case, we have our rotating motion.
