The cytoskeleton is primarily composed of what type of biomolecule?

Answer 1

The cytoskeleton is primarily composed of proteins. It consists of various types of protein filaments, including microtubules (made of tubulin), intermediate filaments (various proteins depending on the cell type, such as keratin), and actin filaments (made of actin). These protein structures play crucial roles in maintaining cell shape, enabling cell movement, and organizing cellular components.
