Dr. Kumar has discovered an enzyme that catalyzes the hydrolysis of lactose into glucose and galactose. What is the most appropriate name for this enzyme according to standard enzyme nomenclature?
A
Amylase
B
Protease
C
Lipase
D
Lactase
검증된 단계별 안내1
Understand the problem: The enzyme catalyzes the hydrolysis of lactose into glucose and galactose. This means the enzyme specifically acts on lactose, a disaccharide sugar.
Recall standard enzyme nomenclature: Enzymes are typically named based on the substrate they act upon and the type of reaction they catalyze. The suffix '-ase' is commonly used for enzymes.
Identify the substrate: The substrate in this case is lactose, a carbohydrate. The enzyme should therefore have a name that reflects its action on lactose.
Match the enzyme name to the substrate: Among the options provided, 'Lactase' is the most appropriate name because it directly indicates the enzyme acts on lactose.
Confirm the reasoning: The other options (Amylase, Protease, Lipase) are incorrect because they refer to enzymes that act on starch, proteins, and lipids, respectively, which are unrelated to lactose hydrolysis.
