Question

Sucrose is hydrolyzed by sucrase into glucose and ________.

1) fructose
2) maltose
3) galactose
4) lactose

Answer 1

Sucrose is hydrolyzed by sucrase to produce glucose and fructose, which are monosaccharides absorbed into the bloodstream during digestion.

Step-by-step explanation:

Sucrose is hydrolyzed by the enzyme sucrase into glucose and fructose. When this disaccharide undergoes hydrolysis, the glycosidic linkage between the glucose and fructose molecules is broken, resulting in the formation of these two monosaccharides. While lactose, another disaccharide, is broken down into glucose and galactose by lactase, and maltose is broken down into two glucose units by maltase, it's important to remember that sucrose specifically yields glucose and fructose.
