Ras signaling - GTPase - promotes growth and proliferation - mutated in 20-30% of all cancers - point mutations are most common G12V mutation - blocks GAP binding - locks RAS in active state, promoting proliferation Q61K mutation - raises activation energy of GTP hydrolysis - blocking hydrolysis, keeping RAS active Hallmarks of cancer 1) self-sufficiency in growth signals 2) insensitivity to anti-growth signals 3) unstable DNA 4) metastasis 5) evasion of apoptos...

dependent upon the overall order of the reaction The units for a rate constant, k, are: dependent upon the overall order of the reaction a rate constant is unitless M^-1 M^-1 s^-1 s^-1 the fraction of collisions with total kinetic energy greater than Ea increases. An increase in the temperature of the reactants causes an increase in the rate of reaction. The best explanation for this behavior is that as the temperature increases, the collision frequency increases. the fraction of coll...
