Process of photosynthesis: the light reactions quimica require. Energy is the ability to use light energy to synthesize. The plants receive light energy is accumulated in the form of ATP and NADPH process is called reactions that require light or plant light reaction, which led to two compounds have to convey energy to the fixation of carbon dioxide. quimica In a reaction that does not require light or dark reaction or Calvin cycle (see Chapter 3) into sugar and other compounds. This chapter has discussed the need for the addition reactions of photosynthesis occur in various ways. But so is generally understood. Here is an example of Photosynthesis in green leaves as an example.
In this reaction, the free energy G is positive, which indicates the adsorption energy and S is negative, which indicates that the entropy decrease is the condition was more organized. Carbon dioxide into carbohydrates is This is a solid G = 686 kcal / mole (endergonic or endothermic reaction) S = -43.6 cal / mole. Degree quimica (entropy quimica decrease) in exposure and color lighting cabin relay power. (Photosystem) We know already that in leaf chloroplasts display. Membrane consisting of two layers within a fluid called stroma (stroma), which is a source of enzymes involved in the reactions do not require light. At the inner membrane is a structure that resembles a cyst called thylakoid (thylakoid), which are overlapping a set called Grass Namco (granum) and found in chloroplasts display. Namco spread the graphite. Between platinum graphite tube connecting the thylakoid called. Stroma thylakoid (stromal thylakoid) quimica on the thylakoid membranes quimica are a group of pigments that receives energy from light. Photosynthesis is a process used in many of the groups will contain several colors. In higher plants contain chlorophyll et chlorophyll quimica b and carotene carotenoids. Sunlight shines green leaves. Some will reflect off Partially penetrate into the leaves. And some, only to be sucked into passenger colored pigments such as chlorophyll mainly serves to absorb light. And transfer of light energy to cascade. Likewise the top of the cone, the power to send to the bottom of the cone. To send to the chlorophyll and pigments in the. Center reaction (reaction center optical systems I and II) There will be an energy loss of light in the form of light and heat, light (Photosystem) groups of pigments are 2 types, each with different abilities. absorbs light at different wavelengths, ie a group of pigments that can receive light energy during peak wavelength of about 700 nm, the optical system I or P700 are a group of pigments that absorb light energy peak. wavelengths around 680 nm light system called II or P680 reactions that require light. Divided into two steps, namely the optical system and the optical system II I II lighting system, lighting system during this phase II reaction centers to obtain energy quimica from light. The electron off And will be broken down. Releasing electrons And moving to renewable quimica electrons loose from P680 Figure 2.4 (see more details in the animation in Figure 2.7 to 2.10), the energy that has been at the center of the optical system II reaction causes electrons of chlorophyll. Have more energy It can fall out of a molecule of chlorophyll. The electrons that come off is the potential quimica for reducing or called with a very high potential of Extraction. This electron flow (flow) to a molecule with potential Extraction under the chain of moving electrons (electron transport chain) as shown in Figure 2.4, the electron quimica optical systems II is stimulated by light and dropped quimica out. have Make enzymes (manganese quimica as an element) that are close together can make it work better as the water molecules are split out. Is oxidized to water becomes oxygen (O 2) and hydrogen, or protons (H +), the equation of Hill.
The electrons from the splitting of water according to the equation above will replace electrons lost from the optical quimica system II due to an energy photons (units of light energy supplied) from the transfer of chlorophyll. Fall is around the R.Hill experiments prove that the process of photosynthesis is oxygen, O 2 was born out of the water.
DCPIP is a substance in the indicator. Which are blue When in a state of oxidation. And colorless when in reduced lighting conditions I P700 I or the optical system is shown in Figure 2.5 In this step P700 to get energy from light. The electron dislodged and passed to a receiver other electrons to an electron acceptor final ferredoxin (Fdx) to be used in generating NADPH Next partially restored by the electrons that come off a roundabout. dating back from the lighting system I electron, partly derived from optical quimica systems II or P680, as further detailed in Figure 2.6 Similarly, a reaction of the light I will be light energy transmitted from chlorophyll. Fall is around When sufficient energy (Wavelength of light, moderate) electrons from chlorophyll of light I would slip away (but in this case no splitting of water) with the potential for reducing the higher electron induced optical system II. and other electrons flow to the carrier. And the potential for reducing the use of light. Capable of reducing or reducing potential. Compare the results of any chemical substance to say that in some way it can be of reducing substances. Other well or how poorly it is that we can create a section. Unit of electric potential is the electron volt (eV) the substance of any kind. (In some manner) has a lower or more negative. quimica Reducing substances can have negative eV or less. To say that the substance with negative eV.
