Suppose that the plasma membrane around a eukaryotic flagellum is opened to reveal the axoneme inside. the radial spokes connecting the peripheral microtubule doublets to the central pair are then broken by chemical treatment and atp is added. what is the expected observation? view available hint(s) suppose that the plasma membrane around a eukaryotic flagellum is opened to reveal the axoneme inside. the radial spokes connecting the peripheral microtubule doublets to the central pair are then broken by chemical treatment and atp is added. what is the expected observation? the axoneme will elongate. there will be normal bending of the flagellum. there will be no movement, because the plasma membrane is not present. there will be no movement, because the ability to use atp is lost.
