The ras protein functions as a molecular switch that is set to its "on" state by other proteins that cause it to expel its bound gdp and bind gtp. a gtpase-activating protein reset the switch to the "off" state by inducing ras to hydrolyze its bound gtp to gdp much more rapidly than it would without this encouragement. thus, ras works like a light switch that one person turns on and another turns off. you are given a mutant cell that lacks the gtpase-activating protein. what abnormalities would you expect to find in the way in which ras activity responds to extracellular signals?
