Enzyme Reaction Hydrogen and oxygen release enormous amounts of energy when they react. Yet, hydrogen and oxygen can be mixed together in a balloon and nothing will happen. Why? The energy of activation to form the transition-state complex is too high to allow the reaction to occur without assistance Competitive inhibitors are blocking the reaction from occurring in the active site There must be contaminating elements in the balloon that prohibit the reaction from occurring All of these The energy of activation to form the transition-state complex is too high to allow the reaction to occur without assistance Competitive inhibitors are blocking the reaction from occurring in the active site There must be contaminating elements in the balloon that prohibit the reaction from occurring All of these ANSWER DOWNLOAD EXAMIANS APP
