Dcpip in hill reaction
WebThe Hill reaction is the process of reduction of a final electron acceptor by the hydrogen ion of water in presence of light. It results in the production of oxygen. In the organism, the final electron acceptor is NADP +. The rate of Hill reactions can be …

Webinvestigated using the Hill reaction. Dichlorophenolindophenol (DCPIP) can be used to follow the process. DCPIP is a blue dye which turns colourless when it is reduced by accepting hydrogen and electrons. oxidised DCPIP reduced DCPIP blue colourless (a) (i) DCPIP is an artificial hydrogen acceptor that can be used in the Hill reaction. WebIn this investigation, DCPIP (2,6-dichlorophenol-indophenol), a blue dye, acts as an electron acceptor and becomes colourless when reduced, allowing any reducing agent produced by the chloroplasts to be …
WebMay 2, 2024 · The reaction can only occur if the thylakoid membranes are illuminated as the light-dependent stage stops in the dark. DCPIP is blue when oxidised (at pH 7.0) and … It is possible to introduce an artificial electron acceptor into the light reaction, such as a dye that changes color when it is reduced. These are known as Hill reagents. These dyes permitted the finding of electron transport chains during photosynthesis. Dichlorophenolindophenol (DCPIP), an example of these dyes, is … See more The Hill reaction is the light-driven transfer of electrons from water to Hill reagents (non-physiological oxidants) in a direction against the chemical potential gradient as part of photosynthesis. Robin Hill discovered the reaction in … See more Photosynthesis is the process in which light energy is absorbed and converted to chemical energy. This chemical energy is eventually used in … See more The evolution of oxygen during the light-dependent steps in photosynthesis (Hill reaction) was proposed and proven by British biochemist See more • Cell biology • Photophosphorylation • Daniel I.
