The graph illustrates how temperature affects the rate of photosynthesis. Which statement explains the change in the rate of photosynthesis between $15\degree\text{C}$ and $20\degree\text{C}$?
- AChlorophyll is able to transfer more energy in chemicals to energy in light.
- BEnzymes involved in photosynthesis have denatured.
- CKinetic energy of molecules is increasing, resulting in more effective collisions.
- DLight intensity and not temperature is limiting the rate of photosynthesis.
