Investigation : “How Is the Rate of Photosynthesis Measured?” Graphs : Lab Notebook Questions : 1. Which graph would be the most likely result of performing the photosynthesis experiment using fresh chloroplasts placed in light and DPIP? Graph A would most likely result of performing the photosynthesis experiment using fresh chloroplasts placed in light and DPIP. 2. What is the best explanation for graph B? The chloroplasts were denatured and were not able to let any light transmit. 3. What effect would adding more DPIP to each experimental tube have on these results? More DPIP would mean that it would take a comparably longer time to progressively pale the sample. The reaction would slow considerable. 4. What is the role of DPIP in this experiment? DPIP is used in the experiment mainly to visibly see the reactions of sunlight on chloroplasts. Is the electrons are excited because sunlight has been shows upon them, then the DPIP will become paler until it is almost translucent. 5.
