Energy is released during the oxidation of compounds in respiration. How is this energy stored and released as and when it is needed?

Explanation

### Step-by-Step Solution:

1. **Understanding Respiration**: Respiration in plants involves the oxidation of organic compounds (like glucose) to release energy. This process occurs in the mitochondria of cells.

2. **Energy Release**: During the oxidation of these compounds, energy is released. This energy is not used immediately but is captured in a usable form.

3. **Formation of ATP**: The released energy is used to convert ADP (adenosine diphosphate) and inorganic phosphate (Pi) into ATP (adenosine triphosphate). ATP is often referred to as the energy currency of the cell.
