A  Animals manufacture and store glycogen to serve as a reservoir of readily available glucose.

B  liver and muscles contain glycogen molecules

C  In the muscles, glycogen is found in a much lower concentration (1% of the muscle mass), but the total amount exceeds that in liver.

D  liver and muscles contain a large amount of glucose molecule

A  Starch is insoluble in water at room temperature

B  Colorimetric tests for the percentage of amylose and amylopectin are widely used.

C  Cellulose is insoluble in water

D  The iodine solution slips into the coil of the cellulose causing an intense blue-black color.

A  Amylopectin is a long, unbranched linear chain

B  As a result of the bond angles in the α glycosidic linkage, amylose and amylopectin form a spiral, much like a coiled spring.

C  Amylose is a long, unbranched linear chain

D  Amylase, must first break down starch into smaller sugars.
