Write two energy yielding reactions of glycolysis.

Explanation

**Step-by-Step Text Solution:**

1. **Understanding Glycolysis**: Glycolysis is the metabolic pathway that converts glucose into pyruvate, producing energy in the form of ATP in the process. It occurs in the cytoplasm of the cell.

2. **First Energy-Yielding Reaction**:
- The first energy-yielding reaction occurs when 1,3-bisphosphoglycerate (1,3-BPGA) is converted into 3-phosphoglycerate (3-PGA).
- During this conversion, an inorganic phosphate is added to ADP (adenosine diphosphate) to form ATP (adenosine triphosphate).
- **Reaction**:
