A) glycogen in liver and spleen
B) lactic acid in muscles
C) glucose in liver
D) glycogen in liver and muscles
Correct Answer: D
Solution :
In mammals carbohydrates are stored as glycogen in liver and muscles. Glycogen is an insoluble polysaccharide, containing branched amylase chain, when the demand for energy in a tissue increases glycogen is hydrolysed to release glucose. Glucose is the common hexose sugar. It is the direct source of glycolysis where it breaks down to two molecules of pyruvic acid in cytoplasm. The lactic acid in muscles is formed by the lactic acid fermentation of pyruvic acid (the end product of glycolysis).
