The lighting system I or P700 is shown in Figure 2.5 In this step P700 to get energy from light. Th

Was already known that the plant is an important one. Light energy can lead to fixation of carbon dioxide. And build the food stored in organic matter. The process of photosynthesis In addition, know that the plants are in leaf chlorophyll, which is essential for photosynthesis. And produce carbohydrates and oxygen and is also aware that plants have the right structure to how it works.
Conducts photosynthesis occur in various ways. But so is generally understood.
Here is an example of Photosynthesis in green leaves as an example. biomoleculas 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 (entropy decrease).
Group of pigments with 2 types each with the ability to absorb light energy at different wavelengths, ie a group of pigments that can receive light energy wavelengths up to about 700 nm, the light I. or the group P700 pigment which absorbs light energy peak wavelength around 680 nm light system called II or P680.
The lighting system I or P700 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 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.
Reaction that does not use light (dark reaction) or cycle the Calgary Winter (Calvi photosynthesis process of plants n cycle) is the process of carbon dioxide fixation. To organic Which require the use of ATP and NADPH from the light reactions to synthesize sugars. This process occurs in stroma. Which is external thylakoid but within chloroplasts display.
Reaction in the Calgary Winter cycle is divided into three main steps, as shown in Fig. A carbon dioxide fixation step (CO 2) combines with a profit Boulou 1,5 bis phosphate reduced molecular structure with the help of ATP and NADPH to the carbon fixation Wizard of new aid. ATP
Important reaction cycles of Calgary win. Chemical reaction is the first step to fixing CO 2 to R1, 5-BP (ribulose 1,5 bisphosphate) into 3PGA (3-phosphoglyceraldehyde) two molecular gases CO 2 is immobilized by covalent bonds into a single section. organic molecules R1, 5-BP, which is a water-soluble solid. Single bonding occurs because the two reaction steps of CO 2 fixation reactions which release energy from ATP to encourage biomoleculas DG) are very negative. Reduced NADPH molecules and reactions live. Are among the more acidic biomoleculas (Carboxylic acrylic) is a sugar molecule that is among the Al aldehydes and ketones. It is drawn by the principles of chemical equilibrium, Le Chatelier equation to officially pushed to make glucose, which is stable over 3PGA of which are less stable. biomoleculas
It can be seen that as long as the chloroplast are ATP and NADPH post in stroma enough if they can frozen CO 2 enzymes and other components. In unison, the Calgary Winter Cycle Elements is not necessary biomoleculas in the light, so we have a reaction that does not need light again.
