The cytoskeleton is important in all the cellular processes listed below, EXCEPT:

a. locomotion of the cell
b. generate free space with the cytoplasm
c. strengthen the cell mechanically
d. separating the internal compartments into two daughter cells during cell division
e. drive organelles in a constant stream around the cell interior along cytoskeletal tracts

n a folded protein, most of the nonpolar amino acids are buried inside the protein fold, whereas the polar and charged side chains are exposed to the components in the cytosol. This fold is more stable because of the expulsion of nonpolar atoms from contact with water, favoring the interaction of nonpolar atoms with each other. What is the term we use to refer to the nonpolar amino acids?

A. apolar
B. hydrophilic
C. hyrdophobic
D. hydrocarbon
