The painkiller ibuprofen lowers the activity of an enzyme that is involved in the synthesis of prostaglandin. Ibuprofen attaches reversibly to the active site of the enzyme. Which type of enzyme inhibition is shown by this example, and why?
- Acompetitive inhibition because ibuprofen alters the shape of the enzyme
- Bcompetitive inhibition because ibuprofen and the substrate cannot bind at the same time
- Cnon-competitive inhibition because ibuprofen blocks the active site
- Dnon-competitive inhibition because ibuprofen has the same shape as the substrate
