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 is the concentration of G-actin (actin) or the alpha, beta - tubulin complex (microtubules) at which assembly is balanced with disassembly.
