Dcpip isolation medium

Web-DCPIP is reduced - it accepts electrons from chlorophyll in LD reaction -instead of NADP accepting the electrons, meaning NADP is not reduced so less is produced & less ATP as LI & LD is happening less than usual. RP 8 - Method? (5) 1. Put isolation medium into a beaker (which has the same water potential as chloroplasts). 2. WebPut 5 cm3 DCPIP solution + 1 cm3 water + 1 cm3 isolation medium in the tube. Tubes A and B are control experiments. Leave both tubes until the end of your investigation. 9. Set up tube C as follows: Tube C Put 6 cm3 water + 1 cm3 chloroplast suspension in the tube.
