Hello students, in this question we have been provided with a few antibiotics.
00:06
We need to match each antibiotic with their respective mode of action.
00:11
First one is trimethoprim.
00:14
It disrupts folic acid synthesis which is essential for bacterial growth and reproduction.
00:20
By inhibiting folic acid production, trimethoprim prevents bacteria from synthesizing important components necessary for their survival.
00:30
Therefore, the correct match for trimethoprim is option e.
00:35
Moving on to the next antibiotic that is tetracycline.
00:40
Tetracycline works by inhibiting the 30s ribosomal subunit which is responsible for protein synthesis in bacteria.
00:48
By inhibiting the ribosome, tetracycline prevents the synthesis of new proteins thus hindering bacterial growth and replication.
00:58
Therefore, the correct match for tetracycline is option d.
01:03
Moving on to the next antibiotic that is vancomycin.
01:06
Vancomycin is effective against bacteria by inhibiting cell wall synthesis.
01:12
It specifically interferes with the formation of peptidoglycan which is the crucial component of bacterial cell walls...
