Question #1
Consider the following statements about enzymes:
1. They are biological catalysts.
2. They are consumed in the reaction.
3. They lower the activation energy of reactions.
Which of the above is/are correct?
A. 1, 2, and 3
B. 1 and 2 only
C. 1 and 3 only
D. 2 and 3 only

Correct Answer: Option C
