Enzymes that readily hydrolyze starch cannot hydrolyze the
glycosidic linkages found in cellulose. Why is this logical?
a) The geometry of the bonds is different, and the shapes of
enzyme active sites are highly specific.
b) Starch is held together by hydrogen bonding, not covalent
bonding.
c) Cellulose molecules are highly branched, and enzymes are too
bulky to fit.
d) Starch is held together by peptide bonds, not glycosidic
linkages.
