Anabolism is the sum total of all constructive processes

Explanation

### Step-by-Step Solution:

1. **Understanding Metabolism**: Metabolism refers to all the biochemical processes that occur within a living organism. It is broadly categorized into two types: anabolic and catabolic processes.

2. **Defining Anabolism**: Anabolism is the set of metabolic pathways that construct molecules from smaller units. These processes require energy and are responsible for the synthesis of complex molecules like proteins, nucleic acids, and lipids.

3. **Defining Catabolism**: In contrast, catabolism involves the breakdown of complex molecules into simpler ones, releasing energy in the process. This includes processes like digestion and cellular respiration.
