The hydrolytic action of the following enzyme produces pentose sugar

Options

A. Amylase
B. Sucrase
C. Nucleotidase
D. None of these

Answer

To answer the question regarding which enzyme's hydrolytic action produces pentose sugar, we can follow these steps:

### Step 1: Understand the Types of Enzymes
Enzymes are biological catalysts that speed up chemical reactions in the body. In the context of digestion, there are various enzymes that break down different types of biomolecules.

**Hint:** Remember that enzymes are specific to the type of substrate they act on.

### Step 2: Identify the Relevant Enzymes
In the context of producing pentose sugars, we should focus on enzymes that act on nucleic acids (DNA and RNA). The hydrolysis of nucleic acids leads to the formation of nucleotides, which contain pentose sugars.

**Hint:** Think about which biomolecules contain pentose sugars.

### Step 3: Recognize the Role of Nucleases
Nucleases are enzymes that hydrolyze nucleic acids. They break down DNA and RNA into smaller components, including nucleotides, which consist of a nitrogenous base, a phosphate group, and a pentose sugar (either ribose in RNA or deoxyribose in DNA).

**Hint:** Nucleases are key players in the breakdown of nucleic acids.

### Step 4: Conclude the Answer
The enzyme that produces pentose sugar through hydrolytic action is a nuclease. Specifically, both ribonuclease (which acts on RNA) and deoxyribonuclease (which acts on DNA) can be considered correct answers.

**Hint:** Focus on the type of nucleic acid the enzyme acts upon to determine the specific pentose sugar produced.

### Final Answer
The hydrolytic action of nucleases (ribonuclease and deoxyribonuclease) produces pentose sugars.
