Hello students, based on their modes of action, we can predict whether the hypothetical drugs are broad spectrum or narrow spectrum.
00:18
First of all, drug a interferes with peptidoglycan synthesis.
00:40
First of all, peptidoglycan is a component of the bacterial cell wall.
00:52
If drug a interferes with its synthesis, it would primarily affect the bacteria that have peptidoglycan in their cell walls.
01:00
This includes most types of bacteria except for a few exceptions like mycoplasma which lack a cell wall.
01:08
Therefore, drug a would be considered broad spectrum because it targets a structural component common to many bacterial species.
01:26
Then drug b interferes with 70s ribosome function.
01:39
The 70s ribosome is a cellular structure involved with protein synthesis.
01:56
Since ribosomes are found in both prokaryotic and eukaryotic cell, interference with 70s ribosome function would affect both bacteria and eukaryotic cell...
