WebAug 28, 2024 · This is known as the Hill reaction. In the experiment, the mortar/pestle was used to grind the lettuce and the muslin is used to collect the isolation medium. The … WebTerms in this set (16) What is the hill reaction. the purpose of the investigation is to find the effect of different wavelengths of light on the rate of the light - dependant stage of photosynthesis. leaf extract is left in capillary tubes either covered, left open or under coloured filters and this causes some tubes to photosynthesise and ... 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 ... how does god want us to pray

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 ...
