Give the biochemical events occurring in the root nodule of a pulse plant. What is the end product? What is its fate ?

Explanation

### Step-by-Step Solution:

1. **Introduction to Root Nodules**:
- Root nodules are specialized structures found in pulse plants (legumes) that facilitate nitrogen fixation. These nodules house specific enzymes that play a crucial role in converting atmospheric nitrogen into a usable form for the plant.

2. **Nitrogen Fixation Process**:
- The primary biochemical event in root nodules is nitrogen fixation, where atmospheric nitrogen (N₂) is converted into ammonia (NH₃). This process requires the enzyme nitrogenase, which catalyzes the reaction.
