What is the name of a protein that polymerizes into long chains or filaments that form microtubules, hollow fibers that act as a skeletal system for living cells?
Tubulin
The correct answer is Tubulin.
It is not rigid but constantly changes, allowing for cell movement, division, and transport of substances within the cell. The three main components of the eukaryotic cytoskeleton are: Microtubules (formed by Tubulin) Microfilaments (also called Actin filaments, formed by Actin) Intermediate filaments (formed by various proteins depending on cell type, e.g., Keratin, Vimentin) Each component has distinct protein subunits, structures, and roles within the cell, collectively contributing to the cell's structural integrity and dynamic processes.
