Motor proteins provide for molecular motion in cells by interacting with what types of cellular structures?
A) membrane proteins of the inner nuclear envelope
B) free ribosomes and ribosomes attached to the ER
C) components of the cytoskeleton
D) cellulose fibers in the cell wall

Question

Quizplus · Accepted Answer

Motor proteins, such as myosins, kinesins, and dyneins, interact with components of the cytoskeleton, including microtubules, actin filaments, and intermediate filaments, to generate molecular motion within cells. They are responsible for a variety of cellular processes including organelle transport, cell division, and muscle contraction. Membrane proteins, ribosomes, and cellulose fibers do not interact with motor proteins in this manner.
