Question

Motor proteins are transporting cargoes along microtubule "tracks" that run the length of the axon in the neuron diagram below. 3. cell body axon terminal inward transport microtubule axon outward transport 3a. Notice that the two different types of cargoes (black dots and gray dots) are being transported in opposite directions. Given the diagram above, which of the following statements is likely to be false? (a) (b) (c) The gray cargo is attached to dynein. The black cargo and the gray cargo require ATP hydrolysis for their motion. The black cargo moving toward the axon terminal contains a domain that specifically interacts with the tail domain of a particular kind of motor. The black cargo and the gray cargo are moving along microtubules of opposite polarity (d)

Explanation / Answer

D:The black cargo and the grey cargo are moving along microtubules of opposite polarity..
