Explanation / Answer
C. The concentration of subunits in solution at which cyto-skeletal polymers are growing at the plus end and shrinking at the minus end.
An example of critical concentration is the concentration of subunits in solution at which cyto-skeletal polymers are growing at the plus end and shrinking at the minus end, also known as "treadmilling". Both the growing and shrinking ends have different critical point concentrations. No polymerization occurs below the critical concentration. The growing and shrinking ends are in equilibrium with one another.
