A series of reactions which occur to form a compound or degrade a compound put together are called

Options

A. Metabolism
B. Anabolism
C. Catabolism
D. All the above

Answer

To solve the question, we need to understand the terms related to the series of reactions that involve the formation and degradation of compounds. Let's break it down step by step.

### Step-by-Step Solution:

1. **Understanding Anabolism**:
- Anabolism refers to the series of reactions that build or synthesize complex molecules from simpler ones. This process requires energy and is essential for growth and repair in organisms.
- **Hint**: Anabolism is like constructing a building from bricks.

2. **Understanding Catabolism**:
- Catabolism, on the other hand, involves the breakdown of complex molecules into simpler ones. This process releases energy, which can be used by the body for various functions.
- **Hint**: Catabolism is like demolishing a building to recycle the materials.

3. **Combining Anabolism and Catabolism**:
- Both anabolism and catabolism are essential processes that occur in living organisms. They are part of a larger framework of biochemical reactions that maintain life.
- **Hint**: Think of anabolism and catabolism as two sides of the same coin.

4. **Defining Metabolism**:
- The term "metabolism" encompasses both anabolism and catabolism. It refers to all the biochemical reactions that occur within an organism to maintain life, including both the synthesis of compounds and their degradation.
- **Hint**: Metabolism is the overall process that includes both building up and breaking down.

5. **Conclusion**:
- Given the definitions and relationships between these terms, the answer to the question is "metabolism," as it includes both the formation of compounds (anabolism) and the degradation of compounds (catabolism).

### Final Answer:
The series of reactions which occur to form a compound or degrade a compound put together are called **metabolism**.
