Proteins `overset(" x ")underset(H_(2)O)rarr` Aminoacids 'x' is an enzyme found in intestine is

Options

A. Trypsine
B. Pepsine
C. Lactobacilli
D. Amylose

Explanation

To solve the question, we need to identify the enzyme 'X' that converts proteins into amino acids in the intestine. Here’s a step-by-step breakdown of the solution:

### Step 1: Understand the Reaction
The question states that proteins react with an enzyme 'X' in the presence of water (H₂O) to produce amino acids. This indicates that 'X' is a proteolytic enzyme that catalyzes the breakdown of proteins.

**Hint:** Proteins are large molecules made up of amino acids, and enzymes that break them down are called proteases.

### Step 2: Identify the Location
The question specifies that enzyme 'X' is found in the intestine. This is crucial because it narrows down the possible enzymes to those involved in protein digestion in the intestinal tract.

**Hint:** Think about the digestive enzymes that are active in the intestine.

### Step 3: Recall Relevant Enzymes
In the human digestive system, several enzymes are involved in protein digestion:
- **Pepsin**: Active in the stomach, breaks down proteins into peptides.
- **Trypsin**: Secreted by the pancreas into the small intestine, further breaks down peptides into amino acids.

**Hint:** Consider where each enzyme acts and their specific roles in digestion.

### Step 4: Determine the Correct Enzyme
Since the question asks for the enzyme that converts proteins into amino acids specifically in the intestine, we focus on trypsin. Trypsin is secreted in an inactive form (trypsinogen) by the pancreas and becomes active in the small intestine, where it cleaves peptide bonds to produce amino acids.

**Hint:** Remember that trypsin is specifically known for its action in the intestine and is crucial for the final stages of protein digestion.

### Step 5: Conclusion
Based on the above reasoning, the enzyme 'X' that converts proteins into amino acids in the intestine is **trypsin**.

**Final Answer:** Trypsin
