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 … WebApr 6, 2012 · We cannot measure the production of ATP, but we can measure electron transport using the dye, DCPIP. When the reactions relating to electron transport and the creation of an H+ gradient are uncoupled, electron transport proceeds at a faster rate. Therefore, the reduction and therefore color change of DCPIP occurs faster. can i take fresh fruit on a plane

WebSep 13, 2024 · Why is DCPIP used in the Hill reaction? DCPIP 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, and monitor, redox reactions. How is DCPIP reduced? WebDCPIP is useful to demonstrate Hill Reaction of Photosynthesis. Examine the structures of DCPIP above and choose the best answer from the following. A. A is oxidized and can accept electrons. B. A is reduced and …
