Which of the given statements is INCORRECT about glycogen?
  1. (A)It is present in some yeast and fungi
  2. (B)It is present in animal cells
  3. (C)Only -linkages are present in the molecule
  4. (D)It is a straight chain polymer similar to amylase✓ Correct

Answer: (D)

Solution

Glycogen is the glucose store of animal cells and of some yeast and fungi, and it is held together only by -glycosidic linkages, so those statements are correct. But glycogen is heavily branched, not a straight chain, so the claim that it is a straight-chain polymer like amylose is the incorrect one.
