A person who is on antibiotics for long time tends to feel weak. Give reason with respect to cellular metabolism.

Explanation

### Step-by-Step Solution:

1. **Understanding Antibiotics**: Antibiotics are medications used to treat bacterial infections. They work by targeting specific features of bacterial cells, such as their cell walls or membranes.

3. **Impact on Host Cells**: While antibiotics primarily target bacteria, they can also affect the host's (human) cells, particularly the plasma membrane, which is selectively permeable. This means that it controls what enters and exits the cell.
