Black case is an enzyme that is involved in breaking down lactose the sugar in milk which term best describes the role of lactase in the digestion of milk

Answer and Explanation:

Although I was unable to find the multiple choices for the question, here is a simple, summarized explanation:

Lactase is an enzyme that is involved in breaking down lactose the sugar in milk. It is produced by a gene known as the LCT gene.

This enzyme is produced in the small intestine, and its main role is to digest a sugar called lactose, which is present in dairy products such as milk, and then transform it into simpler sugars - glucose and galactose -. This 'transformation' makes it easier for the body to absorb these sugars into the bloodstream and eventually turn them into energy.
