Cov kev cuam tshuam ntawm oxygenic photosynthesis nyob rau hauv algae thiab nroj tsuag tshwm sim nyob rau hauv ib tug tshwj xeeb cell organelle, the chloroplast (saib daim duab 2.1). Lub chloroplast muaj ob daim nyias nyias, uas kaw lub stroma. Nyob rau hauv lub stroma yog ib tug kaw membrane vesicle, lub thylakoid, uas muaj cov lumen.
Qhov chaw nyob qhov twg photosynthesis tshwm sim?
Hauv cov nroj tsuag, photosynthesis tshwm sim hauv chloroplasts, uas muaj cov chlorophyll. Chloroplasts nyob ib puag ncig los ntawm ob daim nyias nyias thiab muaj peb sab hauv daim nyias nyias, hu ua thylakoid membrane, uas ua rau ntev folds hauv lub cev.
oxygenic photosynthesis hauv cov nroj tsuag yog dab tsi?
Thaum lub sijhawm oxygenic photosynthesis, lub zog hloov hluav taws xob los ntawm dej (H2O) rau carbon dioxide (CO 2), los tsim cov carbohydrates. Hauv kev hloov pauv no, CO 2yog "txo," lossis tau txais electrons, thiab dej dhau los "oxidized," lossis poob electrons. Thaum kawg, oxygen yog tsim nrog rau carbohydrates.
Anoxygenic photosynthesis koom nrog dab tsi?
Anoxygenic photosynthesis yog phototrophic txheej txheem uas lub teeb lub zog raug ntes thiab hloov mus rau ATP, tsis muaj oxygen. Yog li ntawd, dej tsis yog siv los ua ib qho khoom siv hluav taws xob. … Anoxygenic phototrophs muaj photosynthetic pigments hu ua bacteriochlorophylls (zoo ib yam lichlorophyll pom hauv eukaryotes).
Thaum twg Anoxygenic photosynthesis?
It arose at the ca 2.4 Ga (billion years ago) 'Great Oxidation Event', ua rau muaj kev hloov pauv ib puag ncig tam sim (Kopp li al. 2005).
