Identify the core question
The question asks for the primary function of enzymes in the human body.
Define what enzymes are
Enzymes are specialized proteins that act as biological catalysts.
Analyze the role of catalysts
Catalysts increase the rate of chemical reactions without being consumed.
Evaluate the given options
- Option A (monitor responses) is related to the nervous system.
- Option B (move the muscles) is the function of muscular tissue.
- Option C (control the breathing rate) is regulated by the brainstem.
- Option D (speed up chemical reactions) matches the definition of a biological catalyst.
Determine the correct choice
Therefore, the primary function of enzymes is to speed up chemical reactions.
