Two molecules of glucose combine to form a disaccharide molecule during a(n) ________ reaction.
A) dehydration
B) hydrolysis
C) hydrogen bond
D) ionic bond
E) inert

Question

Quizplus · Accepted Answer

A disaccharide is formed when two monosaccharides (such as glucose) undergo a dehydration reaction, where a molecule of water is removed and a glycosidic bond is formed between the two monosaccharides. Hydrolysis, on the other hand, is the breaking down of a disaccharide into its constituent monosaccharides, which involves the addition of a water molecule.  Hydrogen and ionic bonds are not involved in the formation of a disaccharide. "Inert" is not a relevant choice.
