which of the following enzymes of interstitial juice does not have direct role in digestion of nutrient?

Options

A. dipeptidase
B. erepsin
C. Enterokinase
D. Maltose

Answer

To solve the question regarding which enzyme of interstitial juice does not have a direct role in the digestion of nutrients, we can follow these steps:

### Step 1: Understand the Role of Enzymes
Enzymes are proteins that act as biological catalysts, speeding up chemical reactions in the body without being consumed in the process. They can be classified into two categories: digestive enzymes and non-digestive enzymes.

### Step 2: Identify Digestive Enzymes
Digestive enzymes are those that directly aid in the breakdown of nutrients, such as carbohydrates, proteins, and fats. Examples include amylase, lipase, and proteases.

### Step 3: Identify Non-Digestive Enzymes
Non-digestive enzymes do not directly participate in the digestion of nutrients. Instead, they may play a role in activating other enzymes or facilitating other processes. An example of a non-digestive enzyme is enterokinase.

### Step 4: Analyze the Options
Given the question, we need to identify which enzyme from the options provided does not directly digest nutrients. Enterokinase is known to activate trypsinogen into trypsin, but it does not itself digest any nutrients.

### Step 5: Conclusion
Based on the analysis, the enzyme that does not have a direct role in the digestion of nutrients is **enterokinase**.

### Final Answer
The correct option is **C: Enterokinase**.
