Dyneins generate movement in cilia and flagella by
A)the dynein moving along its own microtubule,pulling the cell membrane with it.
B)the dynein on one side of the flagella moving along its neighbor's tubule.
C)all dyneins moving along their neighbors' tubules in a synchronized fashion.
D)the dynein pushing on the neighboring tubules,generating movement.

Question

Quizplus · Accepted Answer

Dyneins are protein complexes that bind to microtubules and generate movement by using ATP hydrolysis. In cilia and flagella, dyneins are arranged in pairs and attached to the outer doublet microtubules. The movement is generated by the dynein on one side of the flagella moving along its neighbor's tubule, causing a sliding of the microtubules and bending of the structure. This is called the sliding filament model and is responsible for the movement of cilia and flagella.
