Step 1
C. Enzymes increase the average energy of reactant molecules.
Answer
This statement is incorrect because enzymes actually lower the activation energy required for a reaction to occur. They do not increase the average energy of the reactant molecules; instead, they provide an alternative reaction pathway that requires less energy. Therefore, enzymes facilitate biochemical reactions by making it easier for reactants to convert into products.
