• A.

  Glycogen

  Glucose

• B.

  Chitin

  N-Acetyl glucosamine (NAG)

• C.

  Inulin

  Mannose

• D.

  Mucopolysaccharide

  Amino sugars and other chemically modified sugars

Answer 1

Answer: (C)

Polysaccharides
- Long chain polymers of monosaccharides. - Present in acid insoluble fraction.
- Examples :
$1.$ Cellulose : It is a homopolymer with glucose as unit. Cellulose is found in cell wall of plants, algae, etc.
$2.$ Starch : It is also a homopolymer of glucose. It serve as store house of energy in plant tissues.
$3.$ Glycogen : It is a homopolymer of glucose. It serve as store house of energy in animals.
$4.$ Inulin : It is a homopolymer of fructose.
$5.$ Chitin : It is a complex homopolysaccharide made up of N-acetyl glucosamine (NAG). It is found in the exoskeleton of arthropods and cell wall of fungi.
$6.$ Mucopolysaccharides : These are complex polysaccharides and heteropolymer of amino sugars and other chemically modified sugars.
