We also have a protein known as a Dinan. So Dinan is basically shown by these purple regions here. And Dinan is basically a motor protein. It uses ATP to essentially create a motion of these microtubules. So it's the Dynam that uses ATP to basically slide across our nine doublet microtubules and that creates a bending like motion for this particular eukaryotic flagellum. So the dynamic motor proteins utilize ATP adenosine triphosphate molecules to force the double microtubules to slide against one another, creating a bending like motion and propelling that cell forward.
