Question

colchicine is a drug used to treat a variety of conditions ranging from gout to certain types of cancer. colchicine works by binding to tubulin dimers, which prevents the tubulin dimers from associating with each other. based on this information, which cellular processes is colchicine likely to disrupt? select all that apply.
skeletal muscle contraction
storage of water and nutrients in vacuoules
structural support of the cell
movement of cargo within the cell
incorrect
structural support typically involves the intermediate filament class of proteins. what type of cytoskeletal element does tubulin form?

Explanation:

Tubulin forms microtubules. Microtubules are involved in intracellular transport (movement of cargo within the cell) as motor proteins like kinesin and dynein move along them. Microtubules also contribute to cell shape (structural support in some cases, especially in non - muscle cells where they help maintain cell polarity and overall cell architecture). Skeletal muscle contraction is mainly due to the interaction of actin and myosin (not tubulin - based structures). Storage of water and nutrients in vacuoles is a function related to the vacuole's membrane and osmotic balance, not tubulin.

Answer:

structural support of the cell, movement of cargo within the cell
