Which ofthe following digestive juices has no enzymes

Options

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

Answer

To determine which digestive juice has no enzymes, we can analyze each of the options provided:

1. **Bile**: Bile is produced by the liver and stored in the gallbladder. It contains bile salts, cholesterol, phospholipids, and pigments such as bilirubin and biliverdin. However, bile does not contain any digestive enzymes. Its primary function is to emulsify fats, which increases the surface area for lipase to act on fats.

2. **Gastric Juice**: Gastric juice is secreted by the stomach and contains several enzymes, including pepsin, which is responsible for protein digestion. Therefore, gastric juice does contain enzymes.

3. **Saliva**: Saliva is produced by the salivary glands and contains the enzyme amylase, which begins the digestion of carbohydrates. Thus, saliva also contains enzymes.

4. **Pancreatic Juice**: Pancreatic juice is secreted by the pancreas and contains several important digestive enzymes, such as lipase, amylase, and proteases, which aid in the digestion of fats, carbohydrates, and proteins, respectively.

From this analysis, we can conclude that the digestive juice that has no enzymes is:

**Answer: A. Bile**
