The possibility of realization of «marked» degrees of freedom when the system motion occurs in narrow area of coordinate plane was considered within the framework of a simplest cluster model of an enzyme molecule. Under certain conditions the motion of the system becomes complex and perhaps stochastic and the spectrum of oscillations becomes more rich. The role of the interaction potential curve shapes of the system is discussed. It was shown that energy transfer associated with complicated modulations in a two-dimensional system takes place even for small oscillations with amplitudes approximately equal to 0.1 A°.
