Kepler Oxygen Production Report

Kepler Oxygen Production Report

Q What wavelengths of light worked best for the production of oxygen? Hypothesize why it was those particular wavelengths of light that produced the most oxygen. Why did using the full spectrum of light work best for the production of oxygen? Explain why an increase in carbon dioxide in the Habitation Unit would not result in greater production of oxygen. Your explanation should include a discussion on the light dependent reactions and the Calvin cycle. Explain why a change in pH did not have an effect on the production of oxygen. What did a change in pH effect? The pH was being changed specifically in the stroma, why does this mean that the change in pH would have that effect but not affect oxygen? Why did the addition of Atrazine reduce the production of oxygen? If Atrazine blocked the movement of electrons from photosystem I instead of photosystem II, should you expect different results?

1. The best wavelengths of visible light for photosynthesis fall within the blue range (425–450 nm) and red range (600–700 nm). 2. White light is the most effective light for photosynthesis because it provides a wide range of colored lights for various pigments to use.
