You continuously monitor the photosynthetic oxygen production from the leaf of a plant illuminated by white light. How and why would oxygen production change if you placed filters in front of the light source that transmit (a) only red, (b) only infrared, and (c) only green light onto the leaf?
Hi, I am doing a question on photosynthesis and I have a question about the answer that was provided. The question states: If four molecules of CO2 enter the Calvin cycle, how many molecules of G3P are produced, and how many molecules are exported? I know that each turn makes 2 G3P so it would make 8 molecules. When I read the book it said that 3 turns makes 6 and then 1 is exported, so why does 4 turns make 8 and 4 be exported?
Why is the carbon dioxide concentration a limiting factor of the photosynthesis process? When the carbon dioxide concentration is increased indefinitely is photosynthesis also increased indefinitely?
