Question

Which cytoskeletal motor(s) is/are most likely to mediate the following movements. Explain each answer in a sentence.

A.) Movement of a ciliated bacterium.

B.) Movement of a vesicle from the cis-golgi to the trans-golgi.

C.) Slow axonal transport.

D.) Movement of pigmented granules in cephalopod skin

Answer 1

A.) Movement of a ciliated bacterium. - Dynein Cilia move through the activation of dyenin that mediates the sliding of MTs within a cilium.

B.) Movement of a vesicle from the cis-golgi to the trans-golgi.- COPI carries from cis end of golgi to trans end of golgi

C.) Slow axonal transport. - Kinesin mediates the plus end-directed motion of slow axonal transport

D.) Movement of pigmented granules in cephalopod skin - Kinesin - the MT (-) ends are at the golgi and kinesin is a (+) end directed motor
