What Would Likely Happen to Photosynthetic Efficiency If a New

question 206

Multiple Choice

What would likely happen to photosynthetic efficiency if a new pigment that absorbs light between 500 and 600 nm were incorporated into light-harvesting complexes?

• A) There would be no change in photosynthetic efficiency.
• B) There would be a very small increase in photosynthetic efficiency, because very little additional light would be absorbed.
• C) There would be a big increase in photosynthetic efficiency, because a lot of additional light would be captured as more wavelengths were absorbed.
• D) There would be a very small decrease in photosynthetic efficiency, because the new pigment would interfere with another light-absorbing pigment.
• E) There would be a big decrease in photosynthetic efficiency, because the new pigment would interfere with all photons absorbed.
