Question

lin is a cytoskeletal drug that prevents polymerization od enhances depolymerization 4) of actin (microfilaments). A cell treated with latrunculin would still be able to A) perform amoeboid movement. mlonnent B) form cleavage furrows,- microfilareaty C) contract muscle fibers. D)extend pseudopodia.mi E) move vesicles around the cel. _micnubsle In addition to determining the correct answer, write the type of cytoskeleton that is responsible for each of the above choices. (All parts of the question must be answered correctly for credit.)

Explanation / Answer

Answer

B) FORM CLEAVAGE FURROWS

Examples of microfilaments are actin and myosin

Their functions are

1) cytoplasmic streaming which is responsible for transport of vesicles within the cytoplasm

2)microvilli support

3)psudopodia formation

4) exocytosis and endocytosis

Microtubules:

Examples: tubulin

Functions are

1) cell movement

2)chromosomal movement

3) cell Plate and cell furrow formation

4) centriole formation

5) cillia and flagellum formation

Hence if microfilaments inhibitor is used then function of microfilaments will not occur but function of Microtubules will still be happened.

Option A C D E are the function of microfilaments

Option B is the function of Microtubules
