Question

How do motor proteins called dyneins cause movement of cilia?

Answer 1

Answer;

A dynein molecule performs complex cycle of movement caused by changes in shape of the protein. ATP provides energy.

Step-by-step explanation;

-Dynein is a family of cytoskeletal motor proteins that move along microtubules in cells. They convert the chemical energy stored in ATP to mechanical work. Dyneins travel toward the minus end of the microtubule (towards the center of the cell).

-Dynein transports various cellular cargos, provides forces and displacements important in mitosis, and drives the beat of eukaryotic cilia and flagella.

Answer 2

Dynein is a cytoskeletal motor protein that moves along microtubules in cells. Dynein has the ability to convert the chemical energy stored in ATP (breaking the ATP) to mechanical work and that is the way it enables the movement. Because it moves towards the minus-end of the microtubules, dynein is called "minus-end directed motor". Dynein is attached to a doublet microtubule (which is the elementary structure of cilia) and by moving along an adjacent microtubule, the dynein motors can cause the microtubules to slide against each other and thus make the move of cilia.
