Effect of temperature and pH on enzymes
Biology · Secondary 3 · 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 70°C, no product is formed. What is the most likely reason?
- The enzyme has more kinetic energy at 70°C.
- The enzyme is denatured and its active site changes shape.
- The substrate is completely used up at 70°C.
- The enzyme concentration becomes zero at 70°C.
