Which of the following is incorrect about glycogen?
Correct answer: D. It is a stored form of glucose in plants
- A. It is a stored form of glucose
- B. In glycogen, the right end is reducing and the left end is non-reducing
- C. It is a branched polymer of glucose
- D. It is a stored form of glucose in plants
Explanation
The correct answer is Option D: 'It is a stored form of glucose in plants.' This statement is incorrect because glycogen is the storage form of glucose in animals, not plants. Plants store glucose as starch, not glycogen.Option A is correct because glycogen serves as a glucose reserve, primarily in animals.Option B is correct because the structural arrangement of glycogen allows for both reducing and non-reducing ends, with the non-reducing ends being more numerous.Option C is correct because glycogen is indeed a branched polymer of glucose, which allows rapid release of glucose when needed.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
