Enzymes sometimes ________. (A) increase the amount of energy necessary to initiate a reaction. (B) increase the rate at which a reaction occurs. (C) catalyze reactions that release energy, but not those that consume energy. (D) are always consumed by catalyzing a reaction. (E) reduce the energy released by a reaction by one of four different mechanisms.

Step 1
They do this by lowering the activation energy required for a reaction to occur. (A) Enzymes do not increase the amount of energy necessary to initiate a reaction; they lower the activation energy. (B) Enzymes do increase the rate at which a reaction occurs by Show more…
