The enzyme which catalyse the degradation of noradrenaline can be inhibited by

Options

A. Barbituric acid
B. KBr
C. Iproniazid
D. Ibuprofen

Answer

To answer the question regarding the enzyme that catalyzes the degradation of noradrenaline and how it can be inhibited, we can follow these steps:

### Step 1: Identify the Enzyme
The enzyme responsible for the degradation of noradrenaline is called Monoamine Oxidase (MAO).

**Hint:** Remember that noradrenaline is a neurotransmitter, and its breakdown is crucial for regulating mood and emotional responses.

### Step 2: Understand the Role of Inhibitors
Inhibitors are substances that can decrease or halt the activity of enzymes. In this case, we are looking for substances that can inhibit Monoamine Oxidase.

**Hint:** Think about medications that are used to treat mood disorders; they often work by affecting neurotransmitter levels.

### Step 3: Identify Specific Inhibitors
One well-known inhibitor of Monoamine Oxidase is Ipranizide. This drug is classified as a tranquilizer and is used as an antidepressant. It works by preventing the breakdown of noradrenaline, thereby increasing its levels in the brain.

**Hint:** Consider the types of medications that are used for depression or anxiety; they often target neurotransmitter systems.

### Step 4: Conclude the Answer
The enzyme that catalyzes the degradation of noradrenaline can be inhibited by Ipranizide, which is a non-selective Monoamine Oxidase inhibitor.

**Hint:** Look for drugs that are categorized as MAO inhibitors when considering options for inhibiting noradrenaline degradation.

### Final Answer
The enzyme which catalyzes the degradation of noradrenaline can be inhibited by Ipranizide.
