Give a name of an inhibitor and the name of an enzyme it inhibits and why/how its use is beneficial to society.

The antibiotic Penicillin is an enzyme inhibitor which
interferes in an enzyme activity that occurs in bacteria but not in humans. This makes
it useful as an antibiotic but at the same time it is safe for human consumption as it
does not cause damage to our body.

The biologically active
part of penicillin binds with an enzyme called DD- transpeptidase which helps link the
cells in the cell-wall of bacteria. Due to this, the bacterial cell wall is weakened and
it breaks up. As bacteria grow, the cell wall is constantly broken and reformed, the
enzyme inhibiting action of penicillin interferes in this process and as a result the
bacteria can no longer survive.

This action of penicillin
has made it very useful in curing illnesses caused due to
bacteria.
