The beating of cilia and flagella occurs by means of _______-based _______.
A) dynein; microtubule sliding
B) kinesin; microtubule sliding
C) myosin; microfilament sliding
D) tubulin; microtubule contraction

Question

Quizplus · Accepted Answer

The beating of cilia and flagella involves the use of specialized motor proteins called dynein, which move along the surface of microtubules and cause them to slide past each other. This sliding movement is what leads to the bending and waving motion of the cilia or flagella. Kinesin is another motor protein that moves along microtubules, but it is not involved in cilia and flagella movement. Myosin is a motor protein that works with microfilaments, not microtubules, and tubulin is the protein subunit that makes up microtubules, but it does not directly cause movement.
