d. They can take place at any temperature or pH.FALSE
b. They occur more quickly than reactions without enzymes. TRUE
c. Enzymes are quickly used up during the reactions. FALSE
d. They can take place at any temperature or pH.FALSE
The correct answer is:
b.They occur more quickly than reactions without enzyme
Explanation:
Catalysts decrease the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes further up reactions by reducing activation energy. Many enzymes change shape when substrates bind.
