Options

A. Allergic conditions are cured by anti-histamines .
B. Hormones are continuously produced but not stored in the body.
C. The function of the white blood cells is to protect the body against infections .
D. Catabolism involves degradation of molecules .

Explanation

To determine which statement is not true, we will analyze each of the four statements provided in the question:

1. **Statement 1**: Allergic conditions are cured by antihistamines.
- **Analysis**: Antihistamines are indeed used to relieve symptoms of allergic reactions, such as itching and swelling, by blocking the action of histamines. Therefore, this statement is true.

2. **Statement 2**: Hormones are continuously produced but not stored in the body.
- **Analysis**: This statement is incorrect. While some hormones are produced continuously, many hormones are produced in response to specific signals and can be stored in glands until needed. For example, insulin is produced by the pancreas and can be stored. Thus, this statement is false.

3. **Statement 3**: The function of white blood cells is to protect the body against infections.
- **Analysis**: This statement is true. White blood cells, or leukocytes, are a crucial part of the immune system and are responsible for defending the body against infections and foreign invaders.

4. **Statement 4**: Catabolism involves degradation of molecules.
- **Analysis**: This statement is also true. Catabolism refers to the metabolic pathways that break down molecules into smaller units, releasing energy in the process.

**Conclusion**: The statement that is not true is **Statement 2**: "Hormones are continuously produced but not stored in the body."
