The graph illustrates how temperature affects an enzyme-controlled reaction. Which statement describes the effect of temperature on this reaction?
- AAs the temperature increases to 25^{\circ}C, the reaction speeds up.
- BBetween 10^{\circ}C and 20^{\circ}C, the enzyme denatures.
- CBetween 35^{\circ}C and 45^{\circ}C, frequency of effective collisions increases.
- DThe optimum temperature for this reaction is 40^{\circ}C.
