What is the role of enzymes in the body?

To produce energy
To break down proteins
To break down carbohydrates
To speed up chemical reactions

The correct answer is: To speed up chemical reactions

Enzymes play a vital role in the body by speeding up chemical reactions. They act as catalysts, reducing the activation energy needed for a reaction to occur. This allows our body processes to occur at a faster rate, such as breaking down food for nutrients and producing essential molecules. Options A, B, and C are incorrect as they are functions of other metabolic processes and not specific to enzymes. For example, energy production is primarily carried out by the mitochondria, while protein and carbohydrate breakdown involves a variety of enzymes and other molecules.
