anabolism : photosynthesis :: catabolism : …………….

Explanation

To solve the analogy "anabolism : photosynthesis :: catabolism : …………….", we need to understand the relationship between the terms involved.

1. **Define Anabolism**: Anabolism is a metabolic process where simple molecules are combined to form complex molecules. This process requires energy, often in the form of ATP.

2. **Identify the Example of Anabolism**: Photosynthesis is a key example of an anabolic process. In photosynthesis, carbon dioxide (CO2) and water (H2O) are converted into glucose (a complex molecule) using sunlight as energy.

3. **Define Catabolism**: Catabolism is the opposite of anabolism. It is a metabolic process where complex molecules are broken down into simpler molecules. This process releases energy, which is often captured in the form of ATP.
