The bending movements of cilia and flagella
A) are associated with microtubules and kinesin
B) involve the alternate assembly and disassembly of actin filaments
C) are produced by the sliding of adjacent microtubule doublets past each other
D) involves dynein action on microfilaments
E) involves myosin action on microfilaments

Question

Quizplus · Accepted Answer

The bending movements of cilia and flagella are produced by the sliding of adjacent microtubule doublets past each other. This is due to the action of dynein motors which move along microtubules and use the energy from ATP hydrolysis to cause the sliding movement.
