問題詳情
50.The Xenopus melanocyte contains melanosomes, the site for the synthesis and storage of melanin, the most common light-absorbing pigment found in animals. As illustrated in the following diagram, these melanosomes aggregate around the perinuclear region upon hormonal stimulation. What kind of cytoskeletal motor is responsible for the movement of melanosomes from the diffusive pattern to the aggregated pattern near the perinuclear region?
(A) ATP-driven Kinesin 1 moving on microtubules.
(B) GTP-driven Kinesin 5 moving on actin filaments.
(C) ATP-driven Myosin 4 moving on actin filaments.
(D) ATP-driven Dynein moving on microtubules.
(E) ATP-driven KIF2A moving on intermediate filaments.
