Abstract. Monte-Carlo simulations of Michaelis-Menten enzymatic reactions occurring in two-dimensional unobstructed media reveal non-classical kinetics reflected by time dependent rate coefficients. A comparison between different equations proposed to describe rate coefficient time dependence is made and the initial conditions influence is also analyzed.
Key words: enzymatic reactions, rate coefficients, two-dimensional media, anomalous diffusion.
