Multiple Choice
Emerson and colleagues discovered the enhancement effect while studying photosynthesis in green algae.The algae were illuminated with light of either 680 nm or 700 nm,and the rate of photosynthesis was measured.The researchers found that the rate of photosynthesis when the lights were applied simultaneously was greater than the sum of the rates when the lights were applied individually.These results provided evidence that
A) photosynthesis is carried out by two photosystems that act in parallel.
B) photosynthesis is carried out by two photosystems that act in series.
C) photosynthesis is carried out by two photosystems that work best at a wavelength of 690 nm.
D) photosynthesis is enhanced by the use of two photosystems.
