Question

sucrose is made of which simple sugars?
glucose and fructose
fructose and galactose
galactose and cellulose
cellulose and glucose

Explanation:

Sucrose is a disaccharide. In biochemistry (a subfield of Biology, which is under Natural Science), disaccharides are formed by the combination of two monosaccharides (simple sugars). Sucrose is formed from the condensation of glucose and fructose. Fructose and galactose form lactose? No, lactose is glucose and galactose. Cellulose is a polysaccharide, not a simple sugar, so options with cellulose are incorrect. So the correct pair is glucose and fructose.

Answer:

A. glucose and fructose
