Treatment of Isolated Spermaxonemes with 0

Multiple Choice

Treatment of isolated spermaxonemes with 0.6 M NaClhas been shown to selectively remove the outer arms from the A microtubules of the axoneme, leaving the inner arms in place. What would be the most likely effect on the NaCl-treated axoneme when ATP was added to the medium?

A) The axoneme would fall apart completely.
B) The axonemes would beat at about half the rate of the intact axoneme.
C) The central microtubules would disassemble leaving the rest of the axoneme intact.
D) The axoneme would be solubilized.
E) Every element of the axoneme would be permanently cross-linked.
