What is the effect of darkness on the reduction of dpip

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. The effect of darkness is that no reaction will occur. What is the effect of boiling the chloroplasts on the subsequent reduction of DPIP?

(a) Which electrode of a voltaic cell, the cathode or the anode, corresponds to the higher potential energy for the electrons? (b) What are the units for electrical...This latter is called a "dark" reaction although it can go on in the light. Blackman theorized that at moderate light intensities, the "light" reaction limits or "paces" the entire process. In other words, at these intensities the dark reaction is capable of handling all the intermediate substances produced by the light reaction.

You also will measure the rate of photosynthesis in isolated chloroplasts. The measurement technique involves the reduction of the dye, DPIP. The transfer of electrons during the light-dependent reactions of photosynthesis reduces DPIP and changes its color from blue to colorless. Objectives Darkness effects the reduction of DPIP. DPIP will not be reduced if there is darkness. This is because when light strikes the chloroplasts, electrons boosted to high energy levels reduce DPIP. Boiling the chloroplasts effects the reduction of DPIP. Boiling chloroplasts would denature the protein molecules that are used to absorb light.
