Questions: Question 15 1 pts Which of the following is a polysaccharide that serves as a storage form of energy is muscle and liver cells? Cellulose Ribose Lipids Glucose Glycogen

The answer is the last one (Glycogen): Glycogen.

Explanation for each option:

1. Cellulose: This is a polysaccharide, but it serves as a structural component in the cell walls of plants, not as a storage form of energy in muscle and liver cells.

2. Ribose: This is a monosaccharide, specifically a five-carbon sugar, and is a component of RNA, not a storage form of energy.

3. Lipids: These are a broad group of molecules that include fats, oils, and hormones. While they are important for energy storage, they are not polysaccharides.

4. Glucose: This is a monosaccharide, a simple sugar that is a primary source of energy for cells, but it is not a polysaccharide.

5. Glycogen: This is a polysaccharide that serves as a storage form of energy in muscle and liver cells. It is the correct answer.

Summary: Glycogen is the polysaccharide that serves as a storage form of energy in muscle and liver cells.
