Lactose is composed of ________ and glucose.

Correct option is C

The correct answer is (c) Galactose.
· Lactose, commonly known as milk sugar, is a disaccharide composed of one molecule of galactose and one molecule of glucose. It is found primarily in milk and dairy products and is broken down by the enzyme lactase in the human digestive system.
Information Booster:
· Lactose Intolerance: Occurs when individuals have low levels of lactase, the enzyme that breaks down lactose into glucose and galactose, leading to difficulty digesting dairy products.
Other Disaccharides:
· Sucrose: Composed of glucose and fructose.
· Maltose: Composed of two glucose molecules.
· Fructose: Not a part of lactose, but it is a component of sucrose.
