What is the effect of boiling chloroplasts on the subsequent reduction of DPIP? Why wasn't dpip added to cuvette 1? Are chloroplasts able to reduce DPIP when kept in the dark? Electron capture by DPIP? What is the purpose of DPIP in the experiment?

What molecule found in the chloroplast does DPIP replace in this experiment? What is the effect of boiling the chloroplast on the subsequent? What role DPIP plays photosynthesis? What is the function of DPIP in this experiment? What is the source of the electrons that will reduce DPIP? What is the function of DPIP? What does DPIP stand for? Last Updated: 10th May, When the light shines on the active chloroplasts, the electrons are excited, which causes them to jump to a higher energy level thus reducing the DPIP.

Enaitz Zurloh Professional. What factors are involved in the separation of pigment? The factors involved in the separation of pigments are the solvent and the amount of hydrogen bonding the pigment has to the cellulose. Chlorophylls contain oxygen and nitrogen bonds, which hold more tightly to the paper; it does not make up as much as carotene, which does not form hydrogen bonds. Weifang Drassal Professional.

What does DPIP stand for? Jesenia Wiertel Professional. What is the main photosynthetic pigment? Chlorophylla-a is the primary pigment for photosynthesis in plants, but the range of light absorption is extended by chlorophyll-b, beta-carotene and other accessory pigments. The variations of chlorophyll-b and the bacterial version are indicated above.

Remedios Haustov Explainer. What happens when you boil chloroplasts? When chloroplasts are boiled , the enzymes that are needed for photosynthesis denature. Without this reduction reaction, the light reactions of photosynthesis cannot occur. Madhu LVI Explainer. How do you make a DPIP solution?

To prepare the DPIP 2,6-dichlorophenol-indophenol solution , add 0. Store this solution in a dark bottle and refrigerate. Marcelin Goodacre Explainer. What are the roles of the other pigments? Other functions of pigments in plants include attracting insects to flowers to encourage pollination. Plant pigments include many molecules, such as porphyrins, carotenoids, anthocyanins and betalains. All biological pigments selectively absorb certain wavelengths of light while reflecting others.

Anmol Meyring Pundit. At first there is a linear reduction indicated by the negative slope of DPIP. The curve began to level off, indicating that the rate of reduction of DPIP was tapering off. How would the presence of DPIP affect the production of oxygen during the light reaction? How would the presence of DPIP affect the production of organic product during the dark reaction?

Using an artificial electron acceptor will allow for the production of oxygen during the course of the light reaction.

However, without the formation of NADPH2, the dark reaction will not occur and organic product will not form. The phenomena described in question 6 was the basis for separating the light reaction from the dark reaction. Hill used ferricyanide, however, as an artificial electron acceptor.

He is credited with isolating the light reaction. Analyze the slopes and discuss your results. In such an experiment several cuvettes are set up similarly to the one kept in the light in the experiment the students just did.
