protein is described by the following e breaks down lactose into
glucose and galac A) Structural B) Transport C) Hormone D) Enzyme E)
Protection
Expert Answer
Answer:
Option D. Enzyme
Lactase is the enzyme that breaks down lactose into glucose and galactose. All enzymes are proteins and hence lactase is a protein. This enzyme in small intestine breaks down the disaccharide lactose into simple sugars glucose and galactose. These monosaccharides are absorbed into the blood stream and turned into energy.
The enzyme lactase is not a structural or transport protein and not a hormone. Also it has no role in providing protection. So options A, B, C and E are incorrect.
Hence the correct answer is option D.
