For most plants, two distinct photosystems (Photosystem I and Photosystem II) work together in series during photosynthesis. These photosystems are complexes of proteins and pigment molecules.
Statement 1: Photosystem I has an absorption maximum of 680 nm, whereas Photosystem II has an absorption maximum of 700 nm.
Statement 2: The special pair of chlorophyll a molecules in the reaction center of photosystem I is designated as P700, whereas the special pair of chlorophyll a molecules in the reaction center of photosystem II is designated as P680.
Statement 1 is true. Statement 2 is false.
Statement 1 is false. Statement 2 is true.
Both statements are true.
Both statements are false.
What enzyme fixes CO2 in the cytosol of a mesophyll cell in a C4 plants?
Why is the C4 photosynthesis called C4 photosynthesis?
1) Evolution led to the formation of RuBisCO that is used by C3 plants to fix CO2. Why do you think that it led to an enzyme that also binds to O2 (which causes photorespiration that isn't beneficial to the plant)?
2) Explain what is meant by the statement: "C4 plants separate C3 and C4 processes in space and CAM plants separate C3 and C4 processes in time."

- Melvin Calvin and Andrew Benson determined the steps in the light-independent reactions of photosynthesis by exposing the green alga Chlorella to CO2 labeled with the radioisotope carbon 14. By looking at which compounds the C14 ended up in, they were able to identify all intermediates in this cyclic pathway. Why did they predict correctly that the same set of intermediates would be formed in the light reaction in land plants?arrow_forwardW hen a culture of Chlamydomonas is exposed to HIGH intensity light, the cells will display negative phototaxis and move away from the light.

The students later went on a hike and located a plant they had never seen before and were interested in how the photosynthesis rates would compare to their experiment with spinach chloroplasts. They extracted chloroplasts of the unknown green-leaved plant and exposed them to the same experimental conditions as before. The students calculated the ΔA620 to be 0.100.
