Question

How much ATP can be generated per one molecule of cellobiose you consume?

Answer 1

Cellobiose has two molecules of glucose that are linked by a $\beta-(1,4')$ glycosidic bond. It therefore undergoes mutarotation due to a aglycone which is hemiacetal. Cellobiose has eight free alcohol $(OH)$ groups, one acetal linkage and one hemiacetal linkage, which give rise to strong inter- and intramolecular hydrogen bonds. Cellobiose therefore produces $-62kJ/mole$ of energy.
