The influence of substrate concentration on an enzyme-catalysed reaction was recorded under three separate conditions: • with no inhibitor • with a competitive inhibitor • with a non-competitive inhibitor. The graph illustrates the outcomes. Which statement is correct?
- AX is a competitive inhibitor which binds to a site other than the active site of the enzyme.
- BX is a non-competitive inhibitor which has a similar shape to the active site of the enzyme.
- CY is a competitive inhibitor which has a similar shape to the active site of the enzyme.
- DY is a non-competitive inhibitor which binds to a site other than the active site of the enzyme.
