WebNADPH. The photolysis of water in the absence of CO2 fixation became known as the Hill Reaction. It is associated with Photosystem II (see Figure 7.1). In order to observe Hill activity, reaction vessels must contain functional chloroplast membranes, water, and an electron acceptor. The rate of this reaction is then dependent on light intensity.
