In this experiment, a blue dye (2,6-dichlorophenol-indophenol, or DPIP) will be used to replace NADPH in the light reactions. When the dye is oxidized, it is blue. When reduced, however, it turns colorless. Since DPIP replaces NADP+ in the light reactions, it will turn from blue to colorless when reduced during photosynthesis.
What will be on the x-axis. time in minutes. What is the photosynthesis reaction equation. 6H₂O + 6CO₂ + light energy → C₆H₁₂O₆ + 6O₂. What does the process of photosynthesis involve. use of light energy to convert carbon dioxide and water into sugar, oxygen, and other organic compounds. What are the two stages of photosynthesis.
Oct 27, 2008 · What role DPIP plays photosynthesis? In lab 4, DPIP is an electron acceptor that takes the place of NADP+. When DPIP is reduced, it changes from blue to colorless so you can see that the Calvin
The molecules migrate, or move up the paper, at different rates because of. 1.) differences in solubility. 2.)molecular mass. 3.) hydrogen bonding with the paper. What were in the four test tubes in the Photosynthesis lab? 1.) no DPIP, unboiled chloroplasts.
In this experiment, a blue dye (2,6-dichlorophenol-indophenol, or DPIP) will be used to replace NADPH in the light reactions. When the dye is oxidized, it is blue.

Study with Quizlet and memorize flashcards containing terms like DPIP Lab-If you get a large transmittance for the trial of the cuvette kept in the dark, what might be an explanation?, DPIP Lab-If you get a large change in transmittance for the trial of the cuvette with boiled chloroplasts, what might be an explanation?, DPIP Lab-If only green light were used in the experiment, instead of
In this laboratory you will separate plant pigments using chromatography. You will also 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, changing it from blue to colorless.
Exercise 4B (Photosynthesis)requires one 45-minute laboratory period. This period can be used for the measurement of photosynthesis using the DPIP-reduction technique.

Lab 4 Plant Pigments & Photosynthesis. Introduction: The purpose of this lab experiment was to separate plant pigments using paper chromatography, and to measure the rate of photosynthesis in isolated chloroplasts. Because of capillary action the solvent moves up the paper causing the pigments to become visible at certain distances.
When reduced, it becomes colorless and indicates that photosynthesis is occurring. 2. DPIP replaced the electron acceptor NADP+. 3. The source of the electrons comes from the breaking of bonds in water molecules, or photolysis. The electrons reduce the DPIP that comes from the chlorophyll after light. minutes the experiment was being conducted.
DPIP is a blue compound that is easily reduced. In this experiment, it will take the place of the electron acceptor NADP. When DPIP becomes reduced (accepts an electron), it turns from blue to colorless. So, if photosynthesis is occurring in a solution of chloroplasts and DPIP, the solution should turn colorless.
