Digestion of carbohydrate is affected by-

Options

A. Amylopsin
B. Lipase
C. Erepsin
D. Pepsin

Answer

**Step-by-Step Solution:**

1. **Understanding Carbohydrate Digestion**: Carbohydrate digestion primarily involves breaking down complex carbohydrates (like starch) into simpler sugars (like glucose). This process begins in the mouth and continues in the small intestine.

2. **Identifying Key Enzymes**: The main enzyme responsible for carbohydrate digestion is amylase. In humans, there are two types of amylase: salivary amylase (produced in the mouth) and pancreatic amylase (also known as amylopsin, produced by the pancreas).

3. **Evaluating the Options**:
- **Amylopsin**: This is a pancreatic enzyme that specifically acts on starch, converting it into simpler sugars. Therefore, it directly affects carbohydrate digestion.
- **Lipase**: This enzyme is responsible for fat digestion and does not play a role in carbohydrate digestion. Thus, its presence does not affect carbohydrate digestion.
- **Erypsin**: This is a proteolytic enzyme that acts on proteins, not carbohydrates. Hence, it does not influence carbohydrate digestion.
- **Pepsin**: This enzyme digests proteins in the stomach and has no effect on carbohydrates.

4. **Conclusion**: Based on the evaluation of the enzymes listed, the digestion of carbohydrates is primarily affected by amylopsin (pancreatic amylase). Therefore, the correct answer is option 1: Amylopsin.

**Final Answer**: The digestion of carbohydrates is affected by amylopsin.
