Enzymes That Readily Break Starch Apart Cannot Hydrolyze the Glycosidic

question 2

Multiple Choice

Enzymes that readily break starch apart cannot hydrolyze the glycosidic linkages found in cellulose. Why is this logical?

• A) Cellulose molecules are highly branched, and enzymes are too bulky to fit.
• B) Starch is held together by peptide bonds, not glycosidic linkages.
• C) The geometry of the bonds is different, and the shapes of enzyme active sites are highly specific.
• D) Starch is held together by hydrogen bonding, not covalent bonding.
