Given below are two statements: Statement I: Glycogen is similar to amylose in its structure. Statement II: Glycogen is found in yeast and fungi also. In the light of the above statements choose the correct answer from the options given below
Multiple Choice Options
- A Statement I is true but Statement II is false.
- B Statement I is false but Statement II is true.
- C Both Statement I and Statement II are true.
- D Both Statement I and Statement II are false.
Step-by-Step Verified Solution
Let's analyze the statements one by one:
Statement I: Glycogen is similar to amylose in its structure.
This statement is not correct. Glycogen and amylose are both polysaccharides, but they have different structures. Amylose is a linear polymer of glucose units linked by _-1,4-glycosidic bonds, which makes it a component of starch. Glycogen, on the other hand, is a highly branched polymer of glucose with _-1,4-glycosidic bonds in the linear chains and _-1,6-glycosidic bonds at the branching points. This high level of branching makes glycogen structurally distinct from amylose.
Statement II: Glycogen is found in yeast and fungi also.
This statement is correct. Glycogen is a form of energy storage in many organisms, including animals, plants, bacteria, and fungi. In fungi and yeasts, glycogen serves as a reserve of glucose which can be mobilized when needed.
Therefore, the correct option is:
Option B
Statement I is false but Statement II is true.
