Why are humans not able to digest cellulose? Question 8 options: Humans cannot digest glucose. Humans do not possess the enzyme necessary to hydrolyze the 1→4-β-glycoside linkages found in cellulose. Humans do not possess the enzyme necessary to unwind the helical shape of the cellulose molecule. Humans do not possess the enzyme necessary to hydrolyze the 1→4-α-glycoside linkages found in cellulose. Humans do not possess the enzyme, lactase, to cleave the 1→4-β-glycoside linkages found in cellulose.

Humans and many other animals are unable to break down cellulose into glucose monomers. Humans can, however, break down other polysaccharides, including glycogen and amylopectin, into glucose monomers. From this, it can be deduced that the reason humans cannot break down cellulose into glucose monomers is that humans do not have an enzyme that can cleave A) alpha 1,4 glycosidic linkages. B) alpha 1,6 glycosidic linkages. C) beta 1,4 glycosidic linkages D) beta 1,6 glycosidic linkages E) alpha 1,2 glycosidic linkages.
