Verified step by step guidance1
Step 1: Begin by understanding the term 'enzyme.' Enzymes are biological catalysts that speed up chemical reactions in living organisms without being consumed in the process. They are typically proteins.
Step 2: Analyze the examples provided in the question: lactase and carbonic anhydrase. Lactase is an enzyme that breaks down lactose into glucose and galactose, while carbonic anhydrase is an enzyme that catalyzes the conversion of carbon dioxide and water into bicarbonate and protons.
Step 3: Compare the definitions of the other options: 'Reactant' refers to substances that are consumed during a chemical reaction, 'Substrate' is the specific molecule upon which an enzyme acts, and 'Product' is the substance formed as a result of the reaction.
Step 4: Recognize that lactase and carbonic anhydrase are not reactants, substrates, or products; they are enzymes that facilitate reactions involving these other substances.
Step 5: Conclude that lactase and carbonic anhydrase are examples of enzymes, as they fit the definition and function of biological catalysts.
