Presume that each PTK receptor bound to a growth factor converts 95 molecules of Ras protein into GTP forms in 1 second as well as each GTP-bound Ras protein activates 12 Raf kinases in 1 second. Compute how many active Raf kinases will be produced in three seconds after activation of PTK in the absence GAP. Presume that Ras hydrolyses GTP with the rate of 2 molecules/min in the absence of GAP
