Question

an enzyme that breaks down lactose. names of enzymes lactase substrate specific

Explanation:

The enzyme that breaks down lactose is lactase. Lactose is the substrate for lactase, and enzymes are specific to their substrates (lactase acts specifically on lactose to break it down into glucose and galactose). So the correct pairing here is that the enzyme breaking down lactose is lactase, and the substrate is lactose (though the table's "Substrate" column with "Specific" might be a bit unclear, but the key is identifying the enzyme for lactose breakdown is lactase).

Answer:

The enzyme that breaks down lactose is Lactase (matching the "Names of Enzymes" to "Lactase" in the table, and the substrate for this enzyme is lactose, with the enzyme being specific to lactose as a substrate).
