Which of the following is FALSE about concerning enzymes?
Correct answer: D. Enzymes increase the energy of product created in a reaction
- A. Substrates must bind the enzyme's active site in order to initiate its effects
- B. Enzymes increase both the forward rate and reverse rate of reaction
- C. Enzymes are not destroyed in a reaction and can be used in the same reaction countless times
- D. Enzymes increase the energy of product created in a reaction
Explanation
Option D is correct since enzymes do not affect the energy of product or reactants(yield). It only increases the rate of both forward and backward reactions. All statements of other options are correct.

About Enzymes
Enzymes are biological catalysts that lower activation energy without being consumed, and their specificity is explained by the lock and key and induced fit models. Work includes the effects of temperature, pH and substrate concentration on reaction rate, plus competitive and non-competitive inhibition and how these differ.
