Photosynthesis

Red and blue light support the highest rates of photosynthesis because

• Only wavelength that carotenoid cannot absorb

• Chlorophylls absorb light of these wavelengths more then other wavelengths

• Light of these wavelengths have the highest energy in the visible spectrum

• Light of these wavelengths activate ATP synthase enzyme
