Synthesis reactions in the body form a division of metabolims called

Options

A. Anabolism
B. Catabolism
C. Chemical reaction
D. None of these

Answer

To answer the question "Synthesis reactions in the body form a division of metabolism called," we need to understand the two main divisions of metabolism: anabolism and catabolism.

### Step-by-Step Solution:

1. **Understand Metabolism**: Metabolism refers to all the chemical reactions that occur within a living organism to maintain life. It is divided into two main categories: anabolism and catabolism.

2. **Define Anabolism**: Anabolism is the process of synthesizing complex molecules from simpler ones. This process requires energy, as it involves forming new chemical bonds.

3. **Define Catabolism**: In contrast, catabolism is the breakdown of complex molecules into simpler ones. This process releases energy, as it involves breaking chemical bonds.

4. **Identify the Correct Answer**: Since the question specifically asks about synthesis reactions, which involve building complex molecules, the correct term is anabolism.

5. **Eliminate Incorrect Options**:
- Catabolism refers to breakdown, not synthesis.
- Chemical reaction is too broad and does not specify the type of reaction.
- "None of this" is incorrect since we have identified the correct term.

Thus, the synthesis reactions in the body form a division of metabolism called **anabolism**.

### Final Answer:
**Anabolism**
