Which of the following has no digestive enzyme ?

Options

A. Saliva
B. Bile
C. Gastric juice
D. Intestinal juice

Answer

To determine which of the following options has no digestive enzyme, we need to analyze each option provided:

1. **Saliva**: Saliva contains the enzyme salivary amylase, which helps in breaking down starch into maltose. Therefore, saliva does have a digestive enzyme.

2. **Bile**: Bile is produced by the liver and is involved in the emulsification of fats, breaking down large fat globules into smaller droplets. However, bile does not contain any digestive enzymes. Its primary function is to aid in the digestion and absorption of fats, but it does not chemically break them down.

3. **Gastric Juice**: Gastric juice is secreted by the stomach and contains enzymes such as pepsin, which digests proteins into smaller peptides. Hence, gastric juice does contain digestive enzymes.

4. **Intestinal Juice**: Intestinal juice, also known as succus entericus, contains various enzymes that help in the digestion of carbohydrates, proteins, and nucleic acids. Therefore, intestinal juice also has digestive enzymes.

Based on this analysis, the only option that does not contain any digestive enzymes is **bile**.

**Final Answer**: Bile has no digestive enzyme.
