Dcpip reduction
Did you know?
WebDCPIP is blue when oxidised (at pH 7.0) and colourless when reduced, so it is possible to monitor the loss of blue colour as an indication that DCPIP has accepted electrons. It can be used to participate in, ... DCPIP can access the thylakoid membranes directly, without having to pass through the outer membranes, to accept electrons directly ... 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.
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 … WebNov 20, 2006 · As photosynthesis occurred, electrons were donated to the DCPIP oxidized, forming DCPIPH 2 reduced. DCPIP oxidized is able to absorb light from the spectrophotometer at 621 nm, hence that it why it was calibrated at 621 nm. As photosynthesis took place, there was less and less DCPIP oxidized available for …
