Which of the following carbohydrate is known as animal starch?

Options

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

Answer

To answer the question "Which of the following carbohydrate is known as animal starch?", we can follow these steps:

### Step 1: Understand the concept of starch
Starch is a carbohydrate that serves as a reserved food material in plants. It is primarily found in sources like potatoes, rice, and wheat.

**Hint:** Recall that starch is the main storage form of energy in plants.

### Step 2: Identify the carbohydrate stored in animals
In animals, the equivalent of starch is glycogen. Glycogen is a polysaccharide made up of glucose units and serves as the primary storage form of energy in animal tissues.

**Hint:** Think about how animals store energy differently than plants.

### Step 3: Define glycogen
Glycogen is stored in the liver and muscle cells of animals and is often referred to as "animal starch" due to its similar function to starch in plants.

**Hint:** Remember that glycogen is crucial for energy storage in animals.

### Step 4: Eliminate other options
If other carbohydrates like cellulose, amylose, or maltose are presented as options, we can eliminate them:
- Cellulose is a structural component in plant cell walls.
- Amylose is a component of starch, not a separate carbohydrate.
- Maltose is a disaccharide made from two glucose units.

**Hint:** Compare the functions of these carbohydrates to determine which one serves as a storage form of energy.

### Conclusion
Based on the above reasoning, the carbohydrate known as animal starch is **glycogen**.

**Final Answer:** Glycogen is known as animal starch.
