Chapter 24.3, Problem 18LC

Interpretation Introduction

Interpretation: The effect of the enzyme on the reaction rates in living things is to be explained.

Concept introduction: Enzymes are present in every living thing. The body naturally produces enzymes.

Answer to Problem 18LC

The enzymes speed up the rate of chemical reactions in living things by acting as catalysts.

Explanation of Solution

Enzymes are biological molecules that function as catalysts to accelerate or speed up the rate at which chemical reactions take place in living things. The rate at which these biological events occur without enzymes is far too low to support life. Enzymes are responsible for catalyzing the biochemical reactions that occur in living organisms.

Conclusion

The enzymes speed up the rate of chemical reactions in living things by acting as catalysts.
