6) Chemical reactions take place when molecules bump into one another with sufficient force to break apart? (True / False)
7) The extra energy needed to start a spontaneous reaction is called the activation energy? (True / False)
8) At normal temperatures and pressures, reacting molecules need extra activation energy to get them moving fast enough to react with one another? (True / False)

20) Product molecules are formed when the substrates react with one another? (True / False)
21) Binding the substrate at the active site lowers the activation energy barrier? (True / False)
22) Any substrate can become a product at the active site of any enzyme? (True / False)
