Question 1
Why is sucrose classified as a non-reducing sugar?
Because it contains only glucose
Because only one anomeric carbon is involved in bonding
Because both anomeric carbons of glucose and fructose are involved in the glycosidic bond
Because fructose is not a monosaccharide
Question 2
The inability of humans to digest Cellulose is primarily due to:
The high degree of branching in the Cellulose molecule
The requirement for symbiotic bacteria found exclusively in ruminants and termites
The lack of the enzyme cellulase that breaks 𝛃 (1 → 4) linkages between glucose monomers
The extensive intramolecular and intermolecular hydrogen bonding within the cellulose chain
