The graph illustrates the effect of temperature on enzyme activity. Which statements about the enzyme and substrate at temperatures 1 and 2 are correct?
- ATemperature 1: The active site fits into the substrate of the enzyme. Temperature 2: The substrate changes shape so that it cannot fit into the active site.
- BTemperature 1: The enzyme and substrate have the same shape. Temperature 2: The enzyme and substrate have different shapes.
- CTemperature 1: The enzyme is denatured. Temperature 2: The enzyme and substrate have complementary shapes.
- DTemperature 1: The substrate fits into the active site of the enzyme. Temperature 2: The active site changes shape so that the substrate cannot fit into it.
