Effect of temperature and pH on enzymes
Biology · Secondary 4 · Medium · Effect of temperature and pH on enzymes
A student investigates the effect of temperature on an enzyme. At 37 °C, the reaction is fast. At 60 °C, the reaction is very slow and does not speed up again when cooled back to 37 °C.
What is the best explanation?
What is the best explanation?
- The enzyme is denatured at 60 °C.
- The substrate is denatured at 60 °C.
- The enzyme becomes inactive but fully recovers on cooling.
- The substrate concentration becomes zero at 37 °C.
