Photosynthesis (Photo Synthesis). The process of photosynthesis is the process by which plants and organisms change in light energy into chemical energy, which is in the form of organic molecules are created. The energy in the organic molecules are used as an energy source in the life of the plants and all living things on the Earth. The process of photosynthesis, this may be regarded as only one of the plants and creatures that can draw energy from the Sun to come in the world.How do solar plants. Plants and/or creature with the photosynthesis process. There must be substance that has the ability to absorb solar energy and apply it to creating chemical bonds (a chemical bond) in organic molecules. The molecule has the ability to absorb the light that exists in plants and creatures, this is the pigment (pigment) pigment that is used in the process of photosynthesis (the photosynthetic pigment) can be divided into several types according to the nature of the molecular structure include:1. Chlorophyll A common pigment in plants and organisms photosynthesis process. The structure consists of a porphyrin-like structure, which has a section that Mg2 + is the central part of the structure and is a long line of hydrocarbons, which is a hydrophobic region which is embedded on the photosynthetic membrane in the chloroplast.2. Phycobilins A pigment that is accessory light-harvesting pigments found in cyanobacteria and red algae have structures as open-chain tetrapyrroles. Phycobilins that is associated with the process of photosynthesis which is known generally, there are 3 types of phycoerythrin (or phycoerythrobilin), allophycocyanin and phycocyanin (or phycocyanobilin) (allophycocyanobilin), which all three types will not be found in Angiosperm, but only found in cyanobacteria and red algae only.3. Carotenoids Groups of pigment that are yellow-orange. Common in plants and creatures can photosynthesis. Have a duty to help solar accessory pigment light-harvesting to photosynthesis, and serves to prevent hazards from light (photoprotective agents). As a group, are yellow-orange pigment. Common in plants and creatures can photosynthesis. Have a duty to help solar accessory pigment light-harvesting to photosynthesis, and serves to prevent hazards from light (photoprotective agents). The main structure of the pigment of this group is to be a line which contains the hydrocarbons, carbon atoms, which can be categorized as 40 2 carotenes and xanthophylls subordinate groups. Carotenes are pigment with an orange or orange-red, as a long line of hydrocarbon part xanthophyll, yellow or orange-yellow, which consists of a long line of hydrogen, carbon, and then also have O as an element which has several kinds of xanthophylls, depending on the level of oxidation of the molecule.The plants and creatures that can photosynthesis. The plants and creatures that can photosynthesis. Both prokaryote and eukaryote groups that include bacteria and other obligations in a prokaryote by light (photosynthetic bacteria) and cyanobacteria they part the eukaryote photosynthesis include various types of algae, MOSS. Ferns, cycads and coniferous plants, which create a pigment that plants and creatures of each kind used in solar modules to be used in the process of photosynthesis, it may vary.The absorption of pigment (Light absorption). Pigment used in the photosynthesis process. Has the ability to suck light in different wavelengths? Natural light is composed of light at different wavelengths of light in the wavelengths we can see (visible light) is located in the wavelengths 400-700 nm.Pigment used in the process of photosynthesis? Considering the structure of the pigment used in the process of photosynthesis, all three groups are found to be sharing the treasure is there part of the molecule that are all low or no polarity, so these molecules are embedded on the inner cell membrane in plants and organisms are prokaryote these pigment is embedded on the photosynthetic membrane in plants and creatures to have organic naen eukaryote groups acting in the photosynthesis process in particular is the chloroplast. คลอโรพลาสต์ส่วนใหญ่ เป็นออร์กาแนลล์รูปร่างกลมรี สามารถเห็นได้ชัดเจนด้วยกล้องจุลทรรศน์ (light microscope) คลอโรพลาสต์มีเยื่อหุ้มเป็น 2 ชั้น คือ เยื่อหุ้มชั้นนอก (outer membrane) และเยื่อหุ้มชั้นใน (inner membrane) ภายในบรรจุของเหลวซึ่งมีเอนไซม์ที่ใช้ในกระบวนการสังเคราะห์ด้วยแสงละลายอยู่หลายชนิด เรียกส่วนของเหลวนี้ว่า stroma เมื่อตัดผ่านคลอโรพลาสต์และศึกษาด้วยกล้องจุลทรรศน์อิเลคตรอน จะพบว่าภายในจะเห็นลักษณะเป็น membrane ซ้อนทับกันอยู่เป็นกลุ่มๆ แผ่นเยื่อ (membrane) ที่อยู่ภายในคลอโรพลาสต์นี้เรียกว่า ไทลาคอยด์ (thylakoid membrane) บางส่วนของไทลาคอยด์จะอยู่ซ้อนทับกันเป็นชั้นๆ เรียกชั้นของไทลาคอยด์นี้ว่า กรานุม (granum) (พหูพจน์คือ กรานา(grana)) หรือ grana lamellae และส่วนที่ไม่ได้ซ้อนทับกันเรียกว่า stroma lamellae หรือ stroma thylakoid thylakoid membrane นี้เองที่เป็นตำแหน่งที่อยู่ของรงควัตถุที่ใช้ในกระบวนการสังเคราะห์ด้วยแสง That is partially the Northwestern area of the Tai la khoi that overlap is considered in detail, it is found that the overlap is a stack that resembles a flat circular bag. Stacked a layer inside the bag with the liquid contained. Get inside the thylakoid space or lumen bag.Mechanisms in the photosynthesis process. In the light energy, chemical energy, in the form of organic molecules it is divided into 2 phases:The backlight (Light reaction).Fixation of carbon dioxide (CO2 fixation reaction). The reaction requires a process that occurs is that Tai la khoi pigment and bring solar energy to create substances that have high energy, including ATP and NADPH in order to get energy from these molecules to create organic substances in the process of further carbon dioxide fixation. Which occur on the point of rama in the chloroplast.The reaction requires the use of light. Different types of pigment that is located on La khoi will stay together as a group by having several proteins due to the island.
