Question

What are the products of the breakdown of lactose by lactase?

Answer 1

Answer:

The correct answer is D. Glucose plus galactose

Explanation:

Lactose is a disaccharide found in dairy. It is made up of monosaccharides: glucose and galactose. Its chemical structure its structure is of β-D-galactopyranosyl- (1 → 4) -D-glucopyranose; a bond occurs between carbon 1 of galactose and carbon 4 of glucose. The lactase enzyme produced by the small intestine (it is a β-galactosidase) decomposes the lactose in these two sugars.
