Which of the following are the enzymes of gastric glands?

Options

A. Trypsin and renin
B. Pepsin and rennin
C. Lipase and trypsin
D. Vasopressin and lipase

Answer

To determine which of the following are the enzymes of gastric glands, we will analyze the options provided:

1. **Understanding Gastric Glands**: The gastric glands are located in the mucosa of the stomach and are responsible for secreting various substances, including enzymes that aid in digestion.

2. **Types of Cells in Gastric Glands**:
- **Mucous Neck Cells**: These cells secrete mucus, which protects the stomach lining.
- **Peptic (Chief) Cells**: These cells secrete pepsinogen, which is an inactive form of the enzyme pepsin. They also secrete renin (in infants), which is involved in milk protein digestion.
- **Parietal (Oxyntic) Cells**: These cells secrete hydrochloric acid (HCl), which activates pepsinogen to pepsin and pro-renin to renin.

3. **Analyzing the Options**:
- **Option A: Trypsin and Renin**: Trypsin is not produced by gastric glands; it is produced by the pancreas. Renin is produced in gastric glands, but this option is incorrect due to trypsin.
- **Option B: Pepsin and Renin**: Both pepsin (activated from pepsinogen) and renin (in infants) are produced by gastric glands. This option is correct.
- **Option C: Lipase and Trypsin**: Lipase is produced by the pancreas, and trypsin is also not produced by gastric glands. This option is incorrect.
- **Option D: Vasopressin and Lipase**: Vasopressin is a hormone produced by the hypothalamus, and lipase is produced by the pancreas. This option is incorrect.

4. **Conclusion**: The correct answer is **Option B: Pepsin and Renin**, as both are enzymes produced by the gastric glands.
