Biology · Secondary 3 · Medium · Effect of temperature and pH on enzymes
The graph of an enzyme’s activity against temperature shows a maximum at 40°C. What happens to the enzyme molecules when the temperature is increased from 40°C to 70°C?
- They become denatured and lose their specific active sites.
- They gain more active sites and work faster.
- They are used up completely in the reaction.
- They change into substrate molecules.
