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.

Internodes

Sections of a plant stem or branch occurring between two successive nodes, which are the points on a stem where leaves or branches originate.

Secondary Growth

Refers to the growth process in plants that results in increased thickness of stems and roots, typically seen in woody plants.

Woody Plants

Plants that produce wood as their structural tissue and typically have perennial growth, such as trees and shrubs.
