Which of the following carbohydrate is known as animal starch?

Options

A. Cellulose
B. Amylose
C. Glycogen
D. Maltose

Answer

To determine which carbohydrate is known as animal starch, we can analyze the options provided:

1. **Cellulose**: This is a polysaccharide that forms the structural component of plant cell walls. It is not involved in energy storage in animals.

2. **Amylose**: This is a component of starch, which is a carbohydrate used by plants for energy storage. It is a straight-chain polymer of glucose, but it is not found in animals.

3. **Glycogen**: This is a branched polymer of glucose that serves as a form of energy storage in animals. It is primarily stored in the liver and muscle cells. Glycogen is often referred to as "animal starch" because it functions similarly to starch in plants, but in animals.

4. **Maltose**: This is a disaccharide made up of two glucose units. It is not a storage form of energy but rather a product of starch digestion.

Based on this analysis, the carbohydrate known as animal starch is **glycogen**.

**Final Answer**: Glycogen
