Verified step by step guidance

Understand the context of the question: The problem is asking about a polysaccharide used for energy storage in human muscle and liver cells. Polysaccharides are long chains of monosaccharides linked by glycosidic bonds, and they serve various biological functions such as energy storage and structural support.

Review the options provided: The options include chitin, cellulose, glycogen, and starch. Each of these is a polysaccharide, but they have distinct roles in biological systems.

Eliminate incorrect options: Chitin is a structural polysaccharide found in the exoskeletons of arthropods and fungal cell walls, not used for energy storage in humans. Cellulose is a structural polysaccharide found in plant cell walls and is indigestible by humans. Starch is an energy storage polysaccharide in plants, not humans.

Identify the correct answer: Glycogen is the polysaccharide specifically used for energy storage in human muscle and liver cells. It is a highly branched polymer of glucose, allowing for rapid release of glucose when energy is needed.

Conclude: The correct answer is glycogen, as it matches the description of the polysaccharide used for energy storage in human muscle and liver cells.
