The prompt asks for the antigas dietary supplement that best completes the statements about two scenarios involving gas and digestion.
First scenario: Harry will eat a lot of broccoli, a high-fiber food, and he takes a supplement prior to dinner to avoid gas. The enzyme that specifically helps break down certain complex carbohydrates found in many high-fiber foods (like beans and cruciferous vegetables) is alpha-galactosidase. This enzyme breaks down oligosaccharides that cause gas, reducing gas production.
Second scenario: Hermione is missing the enzyme lactase, so before she consumes dairy (treacle tart and milk), she takes a supplement to aid digestion of lactose. lactase is the enzyme that digests lactose, the sugar in milk and dairy products; taking a lactase supplement helps prevent lactose-related gas, bloating, or discomfort.
Option-by-option reasoning:
- alpha-galactosidase: This choice is correct for the broccoli scenario because it targets the gas-causing oligosaccharides in high-fiber foods. It does not target lactose digestion, which is why it wouldn’t be the right choice for Hermione’s dairy scenario. The filet of reasoning here hinges on matching the enzyme to the substrate: oligosaccharides in beans/fiber-rich foods vs. lactose in milk.
- lactase: This choice is correct for Hermione’s scenario because lactase breaks down lactose, enabling someone who is lactase-deficient to digest dairy more easily. It would not be the needed supplement for minimizing gas from broccoli, since broccoli’s gas is not due to lactose.
Why these aren’t interchangeable in the given contexts (implications): If Harry used lactase, it wouldn’t address the gas produced by high-fiber components like broccoli, because lactose is not a major component of broccoli. Conversely, using alpha-galactosidase for Hermione wouldn’t help with lactose digestion, since lactase is the enzyme that hydrolyzes lactose into glucose and galactose.
In summary, the first blank should be alpha-galactosidase to mitigate gas from high-fiber foods, and the second blank should be lactase to assist in digesting dairy for someone who lacks that enzyme.
