Give Reasons for the following :

How antibiotics work against bacteria? Do they have any effect on human cells also? Explain.

Antibiotics blocks the biochemical pathways which are responsible for the functioning of the bacteria. For example penicillin blocks the pathway responsible for the making of the cell wall. As a result the growing bacterial cell is not able to make cell wall and dies off easily.

The human cell on the other hand is devoid of cell wall and as such is not affected by penicillin.
