• B. Cofactors.
• C. Coenzymes.
• D. Substrates.
• E. Products.

Answer: (C)

Verified step by step guidance

1. Understand the role of enzymes in biological reactions: Enzymes are proteins that act as catalysts to speed up chemical reactions in the body.
2. Identify the components involved in enzyme activity: Enzymes often require additional non-protein molecules to assist in catalysis.
3. Differentiate between cofactors and coenzymes: Cofactors are non-protein chemical compounds that are bound to an enzyme and are required for the enzyme's activity. Coenzymes are a specific type of cofactor that are organic molecules.
4. Recognize the function of coenzymes: Coenzymes bind to the enzyme and assist in the transfer of specific atoms or functional groups during the reaction.
5. Conclude that coenzymes are the organic non-protein components that aid in enzyme catalysis, distinguishing them from other options like reactants, substrates, and products.
