In given Relationship of oxygen production to flash energy, the first evidence for the interaction between the antenna pigments and the reaction centre, What conclusion can be drawn about based on graph;
a.) several hundred pigments are associated with each reaction centre and that each reaction centre must operate four times to produce 1 molecule of oxygen—hence the value of 2500 chlorophylls per O2
b.) low light intensity of the curve, an increase in the number of photons stimulates a proportional increase in oxygen evolution. Thus, the slope of the curve measures the quantum yield for oxygen production
c.) The quantum yield for a particular process can range from 0 →if that process does not respond to light to 1.0→if every photon absorbed contributes to the process by forming a product
d.) O2 require more than a single photochemical event to be formed, and therefore have a lower quantum yield of formation than the photochemical quantum yield. It takes about ten photons to produce one molecule of O2, so the quantum yield of O2 production is about 0.1
Which of the following statements would be correct relates with graph?
