Lactase is an enzyme that breaks down the complex carbohydrate lactose into glucose and galactose, which can be absorbed by the bloodstream and carried to the body's cells. lactose is found primarily in dairy products.

what would most likely happen to a person who had a shortage of lactase?
the person would develop an allergy for dairy products.
the person's pancreas would not be able to regulate the body's blood glucose level.
the person would be unable to fully digest dairy products.
the person would not be able to digest any carbohydrates.

The best and most correct answer among the choices provided by the question is the third choice "The person would be unable to fully digest dairy products."

People with lactose intolerance are unable to fully digest the sugar (lactose) in milk. As a result, they have diarrhea, gas and bloating after eating or drinking dairy products. ... A deficiency of lactase — an enzyme produced in your small intestine — is usually responsible for lactose intolerance.
