Light photosynthesis lokaci yanayi na tsari

Photosynthesis a matsayin sinadaran sabon abu ne mai tsari a cikin abin da hanyoyin gudanar da mahadi an kafa ta maida martani ruwa da carbon dioxide. An muhimmin sharaɗi ne da wannan tsari kwarara daga cikin haske, da kai tsaye hannu na photosynthetic abubuwa. Domin Flora irin wannan abubuwa ne chlorophyll, kwayoyin - bacteriochlorophyll.

Wannan dauki ta hanyar da yanayi ne Multi-mataki da jimla yanayi. Multistage bayyana a gaskiyar cewa a lokacin photosynthesis matakai faruwa sequentially samun, tana mayar da amfani da samu jimla haske makamashi. Wata irin wannan canji ne da canji na carbon dioxide a cikin kwayoyin halitta. A tsari a cikin abin da akwai babban iko da ATP kwayoyin mahadi kira haske lokaci na photosynthesis. Babban yanayin factor da ya kwarara daga wannan lokaci ne gaban haske makamashi. The inji for tabbatar da wannan canji a matsayin haske lokaci na photosynthesis za a iya schematically wakilci kamar haka. Chlorophyll, wanda aka located a kan membranes a cikin chloroplast na shuke-shuke, garwaya da haske fluxes makamashin hasken rana. Sa'an nan, wannan makamashi na taimaka dangane abubuwa phosphoric acid da abubuwa na ATP da ADP kwayoyin. Duk da haka, a kan wannan haske makamashi aiki ba ya kawo karshen. Baya daukan hotuna zuwa aiwatar Fusion kwayoyin, wannan makamashi sa a gudanar da wani dauki na ruwa tsagawa abubuwa. A nan, da haske lokaci na photosynthesis gudana a wani dauki 2H20 = 4H + + + 4e- O2. Kamar yadda za a iya gani, sakamakon wannan dauki hidima samo asali oxygen wadda sa'an nan ya shiga wani free form a irin wannan yanayi.

A mataki na gaba, a cikin abin da ya gane da haske lokaci na photosynthesis, ne kunnawa da chlorophyll kwayoyin. A wannan tsari, a ƙarƙashin rinjayar haske kamfani mai suna Quanta chlorophyll kwayoyin electron motsa zuwa wani sabon electron matakin a cikin kwayoyin tsarin. Catalysts da electron dako da cewa su ne abubuwa na chloroplast sunadaran. Wucewa ta hanyar jerin data m sunadarai, chlorophyll kwayoyin electron aka tilasta rasa da makamashi, da kuma shi ne ciyar a kan tabbatarwa da redox aiwatar da ATP kwayoyin.

Kamar wancan rasa samar da makamashi da kuma abubuwa (electrons), chlorophyll kwayoyin ake mayar da Bugu da kari na electrons da suke da sakamakon da ya kwarara riga aka ambata a sama tsakiyan nonon dauki na ruwa kwayoyin. Kafa hydrogen a kan aiwatar da tsakiyan nonon da aka hada tare da wani abu wanda yake iya yin da rawar na'ura mai a cikin chloroplast.

Shuke-shuke da sauƙi wanzu a duhu yanayi, Ina nufin idan ya kwarara da haske makamashi samuwa. Saboda haka, photosynthesis daukan wuri da kuma duhu mataki, wanda yana da za'ayi a cikin sarari kwance tsakanin casing da chloroplast thylakoids. Domin wannan lokaci na haske makamashi ba a bukata, da kuma dauki kanta kunshi jerin matakai na canji na carbon dioxide kwayoyin shigar da su da iska. A sakamakon irin wannan rikirkida protrudes samuwar glucose kwayoyin, musamman da kuma sauran hanyoyin gudanar da mahadi. Irin wannan mahadi hada amino acid, nucleotides, kazalika da duk aka sani glycerol.

Bugu da kari ga photosynthesis lokaci rabuwa, rarrabuwa dauke a cikin kimiyya da wannan tsari ta hanyar irin. Babban wadanda su ne C3 photosynthesis, kuma C4 photosynthesis, wanda nuna, bi da bi, da kuma uku daga hudu-fili.
