Feedback inhibition nonlinearity

Generally, the nonlinearity is further relates with autocatalysis, self-inhibition, or a delayed feedback loop etc., which cooperatively acted to play role in chemical oscillations [1, 3]. 

The kinetics of oscillatory chemical reaction must have nonlinearity and their rate equations be supposed to quadrant function of concentration of reactants. The kinetically control reaction steps have two values, (+ve) is associated with autocatalysis and (—ve) value is associated with auto-inhibition feedback loops [1].
