The reactants on which enzyme works are:
Correct answer: C. Substrates
- A. Products
- B. Metabolites
- C. Substrates
- D. Catabolites
Explanation
Enzymes work by acting on substrates and converting them into products. The substrate (reactant which is to be converted into the product) molecule is attached to the active site of the enzyme by non-covalent interactions.

About Mode of Enzyme Action
Enzyme action depends on the active site forming a temporary enzyme substrate complex, then converting substrate into products with lower activation energy. The lock and key and induced fit models explain specificity and binding, while cofactors and changes in enzyme shape can affect catalysis.
