Enzymes increase the speed of a chemical reaction because they? A. increase the temperature to provide necessary boost of energy B. make the reaction more energetically favorable C. raise the activation energy needed to initiate a reaction D. make the reaction spontaneous E. none of the above is a correct choice

Step 1
Enzymes do not increase the temperature; they work by lowering the activation energy of a reaction. B. Enzymes do not change the overall energetics of a reaction; they only affect the activation energy. C. Enzymes actually lower the activation energy needed to Show more…
