State whether the following statements are true or false. All of the molecules available for biosynthesis constitute the metabolic pool.

Answer

To determine whether the statement "All of the molecules available for biosynthesis constitute the metabolic pool" is true or false, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Term "Metabolic Pool":**
- The metabolic pool refers to the collection of all the molecules or metabolites that are available for metabolic reactions within a cell.

2. **Identify Types of Metabolic Reactions:**
- Metabolic reactions can be classified into two main types:
- **Catabolic Reactions:** These reactions involve the breakdown of complex molecules into simpler ones, releasing energy in the process. For example, glucose is broken down into pyruvic acid during glycolysis.
- **Anabolic Reactions:** These reactions involve the synthesis of complex molecules from simpler ones, requiring an input of energy. For instance, the formation of proteins from amino acids is an anabolic process.

3. **Role of Molecules in Metabolism:**
- The molecules in the metabolic pool are essential for both catabolic and anabolic reactions. They provide the necessary substrates for energy production and biosynthesis.

4. **Conclusion:**
- Since the metabolic pool includes all the molecules that are available for biosynthesis (as well as those involved in catabolic processes), the statement is indeed true.

### Final Answer:
The statement "All of the molecules available for biosynthesis constitute the metabolic pool" is **True**.
