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

B  liver and muscles contain a large amount of glucose molecule

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 glycogen molecules

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

B  Cellulose is insoluble in water

C  Starch is insoluble in water at room temperature

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