Q1. Humans can digest starch but not cellulose. This is because the human digestive system lacks enzymes to break which specific type of bond?
Answer: Beta-1,4-glycosidic bonds
Explanation: Cellulose contains beta-1,4-glycosidic linkages which humans cannot digest. Amylose is tempting because it is also a glucose polymer, but it has alpha-linkages.
