Question

Which of the following is a function of microtubules?
A) being part of the spindle apparatus
B) control of metabolism
C) storage of secretory products and lysosomal enzymes
D) intracellular removal of damaged organelles or of pathogens
E) assist in DNA replication

Accepted Answer

Microtubules are important components of the spindle apparatus during cell division, where they organize the chromosomes and facilitate their separation.

Answer: D
 Microtubules also play a role in intracellular transport and mediate the movement of organelles and vesicles. They can be selectively targeted to remove damaged organelles or pathogens from the cell through a process called autophagy.
