<prompt> In the mitogen activated protwin kinase pathway , the activation of RAS is counteracted byProtein kinase CGTPase activating proteinPhosphtidyl inositolInositol triphosphate  <response>: Ref Robbins 9e p286 Activated rasvis present in association with GTP. Enzyme GTPase will degrade GTP to GDO and results in inactivation of RAS. Thus ,GTPase activating protein will counteract the activation of ras
