WebRobert Hill originally completed this investigation in 1938; he concluded that water had been split into hydrogen and oxygen. This is now known as the Hill reaction. You can examine a drop of the sediment extract with a microscope under high power to see chloroplasts. WebOur version of the Hill Reaction experiment is designed to demonstrate the relationship between chloroplasts, light, and the light reaction of photosynthesis. To measure the rate of photosynthesis, we use a blue dye called DCPI. In the presence of active photosynthesis, this blue DCPI is reduced by the free electrons produced by photosynthesis ... list of bands that played woodstock 1999

"WebIn experiment B, the Hill reaction occurred fastest in Tube 2, i.e. the tube with no indicator. The absence of an inhibitor means no blockage of active sites or denaturing of substrate or enzyme. Thus the substrate is free to bind with the chlorophyll, hence a relatively fast rate of reaction. 4. The plateauing of the DCMU curve started quite ... " - Hill reaktion experiment
