Microtubules Are Important for Transporting Cargo in Nerve Cell Axons

Microtubules are important for transporting cargo in nerve cell axons, as diagrammed in Figure 17-20.Notice that the two types of cargo are traveling in opposite directions.Which of the following statements is likely to be FALSE? Figure 17-20

A) The gray cargo is attached to dynein.
B) The black cargo and the gray cargo require ATP hydrolysis for their motion.
C) The black cargo moving toward the axon terminal contains a domain that specifically interacts with the tail domain of a particular kind of motor.
D) The black cargo and the gray cargo are moving along microtubules of opposite polarity.
