Question

Which of the following correctly describes a reaction that forms a disaccharide from two monosaccharides?

A. Cellulose + fructose → maltose

B. Glucose + fructose → sucrose

C. Glycogen + lactose → cellulose

D. Lactose + glucose → galactose

Answer 1

Answer: Option B) Glucose + fructose → sucrose

Step-by-step explanation:

Sucrose, with formula C12H22O11, is a dissacharide (carbohydrates composed of two simple sugars) with glucose and fructose units linked by glycosidic linkage. The glucose and fructose are referred to as monosaccharides.

Thus, the two monosaccharides (glucose and fructose) forms sucrose
