1. c                  2. c    hope this helps

Answer 2

Hi,
Correct answers are:

1) C. the energy required to start the reaction Enzyme lower the activation energy.
2) C. Reactions in cells would be too slow to sustain life. The reaction of carbonic acid formation in cells takes about a hundred years without enzymes. With enzymes, it takes 3 seconds.
