Concept

Problem: The light reactions require the cooperation of two photosystems to power linear electron flow from water to NADP+. Determine whether each process is associated with Photosystem II (PS II) only, Photosystem I (PS I) only, or PS II and PS I. Note that electron transport chain here refers to the electron transport chain between the two photosystems, not the one that functions after PS I.
