Advanced Search Photosynthesis is a highly regulated, multistep process. Photosynthesis has a unique place in the history of plant science, as its central concepts were established by the middle of the last century, and the detailed mechanisms have since been elucidated.
Tube 1 was capped and inverted several times. The Spectrophotometer was calibrated using tube 1, which contained chloroplasts and sucrose only, as the blank, to ensure that any changes in absorbency for the other treatments could be attributed to the reduction of the dye DUCKPIN.
This gives a rate per foot-candle and allows you to compare he effectiveness of the light based on color alone. In tube 2, there is a decrease in the absorption rate when the reaction mix is mixed. In test tube 3, the readings of the absorption rate decreases when in the presence of light.
There is a decrease in reading up till the 60th minute and then the absorbency rate decreases in test tube 4. The readings for the absorption rate increases up till the 30th minute then it would decrease in test tube 6.
In test tube 7, the readings increase up till the 30th minute then it would decrease and increase again. Chlorophyll pigments can only carry out photosynthesis in the presence of sunlight.
The dark chloroplasts and boiled chloroplasts showed some signs of photosynthesis but insubstantial compared to the fully functioning chloroplasts. Boiling most likely damaged denatured the chlorophyll beyond repair, so it functions just like as if it was covered with foil occasionally some stray photons will excite the chlorophyll, but holistically, that is not much at all.
In test tube 5 the Hill Reaction will be analyzed by measuring the light absorbency of DUCKPIN as chlorophyll and the electron transport chain reduce it under exposure to light.
An electron transfer inhibitor, 3- 3,4-decontrolling -1,1 methyl-urea DDCDwhich prevents platitudinous from receiving electrons from the primary electron acceptor, will be present in different concentrations to demonstrate the reduction of DUCKPIN as being a consequence of the splitting of H2O and the transfer of electrons from chlorophyll to the primary acceptor and subsequent molecules of the electron transport chain.
In tube 6 the readings are such as photons are absorbed by the photometers when there is higher light intensity. A higher rate of photon absorption indicates that more electrons are excited in the photometers which leads to a higher rate of photosynthesis. However the readings are not accurate as the reading fluctuates increasing and decreasing when it is supposed to increase steadily this may be due to errors that was done during the experiment, when the absorbency rate was measured after the 60th minute the test tube was not closed this may have caused the reading to drop.
In test tube 7 has high absorbency reading at the end of the 90th minute because green light wavelength is the least effective for photosynthesis.
However the reading decreases at the 60th minute and this may be due to the way the test tubes were placed in the ice, the position of the test tube was altered and maybe only half of the mixture was immersed in ice. This may have caused the difference in the reading as the readings were affected by heat and chloroplast is heat sensitive.
