Answer:
Critical concentration is: a. the concentration of tubulin dimers at which assembly is balanced with disassembly.
Explanation:
The cytoskeleton is a complex network of interconnected filaments and tubules that extends throughout the cytosol, from the nucleus to the inner surface of the plasma membrane. Tubulin may assemble and disassemble simultaneously in a process known as treadmilling. In this process, critical concentracion <em>is the concentration of G-actin (actin) or the alpha,beta- tubulin complex (microtubules) at which assembly is balanced with disassembly.</em>
