To determine which statement is false regarding hormones, let's analyze each statement step by step:
1. **Statement 1**: "Hormones provide chemical coordination, integration, and regulation in the human body."
- **Analysis**: This statement is true. Hormones are essential for coordinating various physiological processes and maintaining homeostasis in the body.
2. **Statement 2**: "Hormones regulate metabolism, growth, development in our body organs."
- **Analysis**: This statement is also true. Hormones play a crucial role in regulating metabolic processes, growth, and development in various organs.
3. **Statement 3**: "Besides hypothalamus, pituitary, pineal, thyroid, adrenal, parathyroid, thymus, GIT, heart, kidney, etc."
- **Analysis**: This statement is true as well. These are all glands and organs that produce hormones and are involved in the endocrine system.
4. **Statement 4**: "Hormones can be used again and again like biocatalysts."
- **Analysis**: This statement is false. Unlike biocatalysts, which can be reused multiple times, hormones are produced in small amounts and are highly reactive. After they exert their effects, they are typically broken down by the liver and kidneys, meaning they cannot be reused in the same way.
**Conclusion**: The false statement is the fourth one: "Hormones can be used again and again like biocatalysts."
