BIS 104 PQ 24 Spring 2010 24. Cargo vesicles have been observed to move along micotubules (MTs) toward the “plus’ end at a rate of approximately 3 micrometers per second. Each “step” by the motor protein responsible for this transport is 8 nanometers (approx the length of one tubulin dimer). a. Which motor protein is required for this process? b. What is meant by a “processive’ motor protein? c. What other molecules would most likely be involved in the transport of a vesicle along a

Unformatted text preview: MT? d. How many “steps” can this motor protein make in one second? e. A neuron has to tranport acetylcholine packaged in a vesicle from near the nucleus, down the axon, to the tip for release at a synapse. The length of the axon is 600 micrometers. Assuming the motor protein doesn’t stumble and fall off the MT, how many minutes will it take to deliver the cargo vesicle? f. What two cytoplasmic parameters might influence the rate of cargo movement?...
