Did you know?
2,6-Dichlorophenolindophenol (DCPIP, DCIP or DPIP) is a chemical compound used as a redox dye. When oxidized, DCPIP is blue with a maximal absorption at 600 nm; when reduced, DCPIP is colorless. DCPIP can be used to measure the rate of photosynthesis. It is part of the Hill reagents family. When exposed to light in a photosynthetic system, the dye is … WebThe light-dependent reactions produce a reducing agent. This normally reduces NADP, but in this experiment the electrons are accepted by the blue dye DCPIP. Reduced DCPIP is colourless. The loss of colour in …
WebAug 28, 2024 · In photosynthesis this is NADP but another one, that being DCPIP can be used in isolated conditions. In this process, the DCPIP which is blue becomes reduced DCPIP which is colourless. 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 … Web- in isolated chloroplasts, DCPIP can be used as an artificial electron acceptor (it out competes endogenous NADP+) - oxidized DCPIP is blue but reduced DCPIP is colorless (if a lot of blue, that means that DCPIP isn't acting …
WebDec 9, 2024 · DCPIP is a redox dye commonly used as a monitor of the light reactions in photosynthesis because it is an electron acceptor that is blue when oxidized and … WebSep 15, 2024 · DCPIP is a redox dye commonly used as a monitor of the light reactions in photosynthesis because it is an electron acceptor that is blue when oxidized and colourless when reduced. Why does DPIP change from blue to colorless? When the dye is oxidized, it is blue. When reduced, however, it turns colorless.
WebIf DCPIP is used in the assay, the complex II enzyme-catalyzed reduction of DCPIP is measured by following the decrease in absorbance due to the oxidation of DCPIP at …
WebNov 1, 2013 · When 100 μM decylubiquinone and 100 μM DCPIP were present (the DCPIP should be reduced by the decylubiquinol product), the rate of DCPIP reduction increased to 0.20 ± 0.007 μmol min −1 mg −1. This value is significantly less than the value from our coupled assay even if the ubiquinone-independent rate is not subtracted. tlauncher arenaWebReport the mean corrected DCPIP reduction rates± SEMfor each condition (same asreported in Table 2 above).Calculate the percentage change between the two means,and conduct an Independent Samples one-tailed t-test on these datainVassarStats.
