Bending of cilia and flagella results from which of the following activities?
A) conformational changes in ATP that thrust microtubules laterally
B) conformational changes in microfilaments
C) contraction by myosin
D) conformational changes in a motor protein called dynein

Question

Quizplus · Accepted Answer

The bending of cilia and flagella is caused by conformational changes in a motor protein called dynein, which is attached to microtubules. Dynein uses ATP to change shape and move, causing the microtubules to slide against each other, resulting in the bending motion.
