We study the dynamic feedback mechanism of the mode-coupling model in a binary liquid in the context of structural Glass transition. The dependence of the dynamic transition point on the mass ratio of the constituents in the mixture is studied from the model equations. The effects of slow structural relaxation on the single particle dynamics are also analyzed. The feedback effects on the tagged particle dynamics from coupling of density fluctuations show that the extrapolated self-diffusion coefficient approaches zero at a low temperature in agreement with simulation results.
