Explanation:
Understanding Antibiotics
Antibiotics are medicines specifically designed to combat bacterial infections. They target and kill prokaryotic cells (bacteria) without affecting human cells, making them essential in treating various bacterial diseases. Here are some key points regarding their use:
- Antibiotics work by attacking specific parts of the bacterial cell, such as the cell wall or protein synthesis mechanisms. This disruption leads to the death or inhibition of bacterial growth.
- Examples of common bacterial infections treated with antibiotics include strep throat, pneumonia, and urinary tract infections.
- It’s important to note that antibiotics are ineffective against viral infections (such as colds or flu) and should be used responsibly to prevent antibiotic resistance.
