The neuronal and muscle cells are full of cytoskeletalproteins.
a) The first part of this question is to thoroughly compare andcontrast the microfilaments and microtubules.
Include the following in your comparison:
the subunits; how the subunits are activated; their motorproteins (including any directionality differences); thefilament/tube structures (at least one similarity and onedifference); one protein(s)/complex/factor for each that isrequired to join the subunits into filaments at the proper locationin the cell; their role in cell motility; their role in celldivision; their role in intracellular transportation; at leastthree additional proteins (not mentioned in earlier comparisons)that connect, assist, modulate, or otherwise affect thesefilaments/tubules; their primary locations in the cell. Point formis perfectly acceptable.
b) Now, compare intermediate filaments to these other two for 4(only four) of these characteristics listed above. It is yourchoice as to which four to compare. Include at least one similarityand one difference, but the other two can be your choice (similaror different).
