ATP-ADP cycle is the basis of metabolism. Comment on this statement with respect to the metabolism in plants.

Explanation

**Step-by-Step Solution:**

1. **Understanding the ATP-ADP Cycle**: The ATP-ADP cycle is a fundamental biochemical process that involves the conversion of adenosine triphosphate (ATP) to adenosine diphosphate (ADP) and inorganic phosphate (Pi), and vice versa. This cycle is crucial for energy transfer within cells.

2. **Metabolism Overview**: Metabolism in plants can be divided into two main types: anabolic and catabolic metabolism. Anabolic metabolism involves the synthesis of complex molecules from simpler ones, while catabolic metabolism involves the breakdown of complex molecules into simpler ones, releasing energy in the process.

3. **Anabolic Metabolism in Plants**: In plants, anabolic processes are essential for building complex molecules such as carbohydrates, proteins, and lipids. These processes require energy, which is derived from the hydrolysis of ATP. When ATP is broken down into ADP and Pi, energy is released, which is then utilized for the synthesis of these complex molecules.
