Verified step by step guidance1
Understand the definition of substrates in enzymatic reactions: Substrates are the molecules upon which enzymes act. They bind to the enzyme's active site and undergo a chemical transformation during the reaction.
Recall the distinction between reactants and products: Reactants are the starting materials in a chemical reaction, while products are the substances formed as a result of the reaction.
Analyze the role of substrates in the reaction: Substrates are the starting materials that enzymes convert into products, which aligns with the definition of reactants.
Consider whether substrates can be classified as products: Substrates are transformed into products during the reaction, but they themselves are not products; they are the initial molecules involved in the reaction.
Conclude that substrates are considered reactants in enzymatic reactions, as they are the molecules that participate in the reaction and are transformed into products.
