| |
| − | feedback3="'''Correct!''' Sulphonamides are competitive antagonists of PABA which is a precursor of folic acid. Bacteria need to synthesise folic acid in order to grow as they are unable to obtain it from their 'diet' like mammals can. Since the bacteria are unable to synthesise RNA or DNA, due to lack of folic acid, their growth is inhibited. However if a drug containing PABA e.g. procaine is used at the same time then the bacteria will have another source of PABA so sulphonamides will not be as effective.
