Which of the following sequences correctly represents the flow of electrons during
photosynthesis?
A) NADPH →→02→CO₂
B) H₂O
NADPH → Calvin cycle
C) NADPH →chlorophyll → Calvin cycle
D) H₂O → photosystem I → photosystem II
E) NADPH electron transport chain → 02
Place these events in the correct order: absorption of electromagnetic radiation by chlorophyll,
synthesis of sugars, utilization of carbon dioxide by Calvin cycle enzymes, synthesis of
NADPH, synthesis of ATP, conversion of water into molecular oxygen.

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.
