Quizplus · Accepted Answer

Keratin is not part of the structure of a cilium. However, the other choices (A, C, D, and E) are all components or associated molecules of the cilium. Specifically, A and E are types of tubulin that make up microtubules in the cilium, C is a protein that connects adjacent microtubules, and D is a motor protein that powers the beating motion of the cilium.
