We observed that the inhibition of enzyme increased with increasing concentrations of the pesticides from 0 to 250 ppm. The Kinetics conformed to the Michaelis-Menten model and a Lineweaver-Burk graph of CAT was drawn. To identify the inhibition type, Vmax and Km were calculated at different concentrations of Deltamethrin, Dichlorvos, Malathion and Lambdacyhalothrin. It was documented that dichlorvos and malathion inhibited CAT competitively, whereas deltamethrin and Lambda-cyhalothrin inhibition over CAT were non-competitive.eninfo:eu-repo/semantics/closedAccessDeltamethrinDichlorvosLambda-CyhalothrinMalathionCatalaseInhibitionPesticideInduced Oxidative StressArticle484720724Q4WOS:000392359600021
