Thereof, what is the role of DPIP?
The function of the DPIP is to change from blue to clear as photosynthesis proceeds and DPIP is reduced, allowing the spectrometer to measure the rate of photosynthesis through the clarity of the DPIP solution. The DPIP replaces the NADP+ molecules in photosynthesis. The source of the electrons is the water.
Secondly, what replaces DPIP in photosynthesis? Since DPIP replaces NADPH in the light reactions, it will turn from blue to colorless when reduced during photosynthesis.
what is the effect of darkness on the reduction of DPIP explain?
The effect of darkness on the reduction of DPIP is that the reaction occurs much slower. This is because the electrons move slower when there is not light, and photosynthesis reactions need light to perform the light reactions.
What is the ultimate source of electrons that will reduce DPIP?
When light strikes the chloroplasts, the DPIP is reduced by the excited electrons from chlorophyll, and it changes from its original blue color to colorless as it accepts the electrons.
