A scientist studied how quickly hydrogen peroxide decomposed. Four experiments were done using different mixtures: substrate only, substrate + enzyme, substrate + enzyme + competitive inhibitor, substrate + enzyme + non-competitive inhibitor. The results are shown in the graph sketch. Which row gives the correct lines for two of the experimental mixtures?
- Asubstrate only: 1; substrate + enzyme + competitive inhibitor: 2
- Bsubstrate only: 4; substrate + enzyme + competitive inhibitor: 2
- Csubstrate only: 1; substrate + enzyme + competitive inhibitor: 3
- Dsubstrate only: 4; substrate + enzyme + competitive inhibitor: 3
