Question

When we eat dairy products, we need ________, the enzyme used to hydrolyze ________ into glucose and galactose. In the absence of this enzyme, we may experience:

A) Amylase; Starch
B) Lactase; Lactose
C) Sucrase; Sucrose
D) Maltase; Maltose

Answer 1

The enzyme needed to hydrolyze lactose into glucose and galactose when consuming dairy products is lactase. Deficiency of lactase can lead to symptoms of lactose intolerance.

The correct option is B) Lactase; Lactose.

Step-by-step explanation:

When we eat dairy products, we need lactase, the enzyme used to hydrolyze lactose into glucose and galactose. In the absence of this enzyme, we may experience symptoms of lactose intolerance.

Lactose, a disaccharide found in milk, is hydrolyzed into its monosaccharide components: glucose and galactose specifically by the enzyme lactase. This process occurs in the small intestine and is crucial for the proper digestion of milk and other dairy products. A deficiency in lactase leads to lactose intolerant symptoms because undigested lactose enters the colon, where it gets fermented by bacteria, causing discomfort such as bloating and abdominal cramps. Therefore, lactase is essential for those who consume milk to avoid lactose intolerance issues.

The correct option is B) Lactase; Lactose.
