The figure below illustrates a model of a signal transduction cascade initiated by ing of a ligand to a membrane bound receptor ligand inactivated molecules A partial model of a signal transduction pathway A B C receptor protein A Based on the figure which of the following describes the most likely outcome of a mutation that changes the intracellular region of receptor protein A D activated molecule 1 activated molecule 2 activated molecule 3 The receptor will not activate molecule 1 but the activation of molecules 2 and 3 will continue at lower rates Molecule 1 will not become activated preventing the activation of molecules 2 and 3 and the subsequent cellular response The ligand will not be able to bind the membrane bound receptor preventing the signal transduction pathway from initiating The ligand that binds to protein A will not enter the cell preventing the cellular response from occurring
