Question

In fungi, the food material is stored in the form of
A. Starch
B. Fructose
C. Sucrose
D. Glycogen

Answer 1

Hint:- Glycogen is also known as animal starch. It is a polysaccharide. Fructose is a monosaccharide. It cannot be broken down further. Sucrose is the table sugar. It is a disaccharide formed by the combination of a molecule of glucose and a molecule of fructose. Starch is a polysaccharide and is usually the form in which plants store their food material.

Complete Answer:-
Glycogen is the form in which animals and fungi store their food. It is the chief storage form of polysaccharide in these two kingdoms. It is composed of several glucose molecules. Thus glycogen can be broken down into several molecules of glucose.
Glycogen is a branched polysaccharide. It is the energy source in animals, fungi and even bacteria. A molecule of glycogen contains about 30000 glucose units. It is a short -term energy reserve.
Fungi are heterotrophic which means that they do not make their food but obtain their nourishment from some outside source. They absorb carbohydrates from the substrate and store it in the form of glycogen. In fungi, the glycogen is stored as oil globules.

Thus the correct answer is (D) Glycogen.

Note:- In humans, glycogen is mainly stored in the liver and the skeletal muscles. In skeletal muscles, it is present in a lower concentration than the liver. The uterus stores glycogen during pregnancy to nourish the embryo. Trace amounts of glycogen are also found in the kidneys, the red blood cells, the white blood cells, the glial cells and the brain cells.
