Question

In flagellar motion the motor protein “walk” along the surface of the filament. What does it carry along as its “cargo”?

Select one:

- Linker arms

- Vesicle

- Radial spokes

- A microtubule

- Plasma membrane

Answer 1

In this context, remember that small molecules such as glucose are able to diffuse and they do not need a motor protein to transport them. However, larger molecules that are synthesized in the cell required to be transporter enclosed in a vesicle. This vesicle is transported by the action of motor proteins such as the kinesin which walks unidirectionally long the microtubule filaments. These motor proteins function by the hydrolysis of ATP. So, the correct answer is vesicle
