Among the following how many enzymes are present in intestinal juice: Lipases, nucleases, sucrase, maltase, dipeptidases, invertase, lactase, nucleosidases

Options

A. 5
B. 6
C. 7
D. 8

Explanation

To determine how many enzymes are present in intestinal juice from the given list, we will analyze each enzyme one by one:

1. **Lipases**: Lipases are indeed present in intestinal juice. They help in the digestion of fats.
- **Hint**: Lipases break down fats into fatty acids and glycerol.

2. **Nucleases**: Nucleases are not present in intestinal juice; they are primarily found in pancreatic juice, which aids in the digestion of nucleic acids.
- **Hint**: Nucleases are responsible for breaking down nucleic acids like DNA and RNA.

3. **Sucrase**: Sucrase is present in intestinal juice. It breaks down sucrose into glucose and fructose.
- **Hint**: Sucrase is an enzyme that helps digest sugar.

4. **Maltase**: Maltase is also present in intestinal juice. It converts maltose into glucose.
- **Hint**: Maltase specifically targets maltose, a sugar derived from starch.

5. **Dipeptidases**: Dipeptidases are present in intestinal juice and are responsible for breaking down dipeptides into amino acids.
- **Hint**: Dipeptidases work on proteins that have been partially digested.

6. **Invertase**: Invertase is not present in intestinal juice; it is more commonly associated with yeast and is involved in the hydrolysis of sucrose.
- **Hint**: Invertase is often used in the food industry for sugar processing.

7. **Lactase**: Lactase is present in intestinal juice. It is crucial for the digestion of lactose, the sugar found in milk.
- **Hint**: Lactase helps individuals digest dairy products.

8. **Nucleosidases**: Nucleosidases are present in intestinal juice and help in the breakdown of nucleosides into nitrogenous bases and sugars.
- **Hint**: Nucleosidases are important for nucleic acid metabolism.

Now, let's summarize the findings:
- Present in intestinal juice: Lipases, Sucrase, Maltase, Dipeptidases, Lactase, Nucleosidases (Total: 6)
- Not present in intestinal juice: Nucleases, Invertase

Thus, the total number of enzymes present in intestinal juice from the given options is **6**.

**Final Answer**: 6 enzymes are present in intestinal juice.
