Nyob hauv cov nroj tsuag, algae thiab cyanobacteria, photosynthesis tso pa tawm. Qhov no hu ua oxygenic photosynthesis. … Hauv cov nroj tsuag, algae thiab cyanobacteria, photosynthesis tso oxygen. Qhov no hu ua oxygenic photosynthesis.
Dab tsi tuaj thawj oxygenic lossis oxygenic photosynthesis?
Cov huab cua tau pom meej tias muaj oxygenated txij thaum 'Great Oxidation Event' ca 2.4 Ga dhau los, tab sis thaum lub photosynthetic oxygen ntau lawm pib yog debatable. Txawm li cas los xij, cov pov thawj geological thiab geochemical los ntawm cov pob zeb qub sedimentary qhia tau hais tias oxygenic photosynthesis hloov zuj zuszoo ua ntej qhov xwm txheej oxygenation.
oxygenic photosynthesis tshwm sim nyob qhov twg?
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.
YPuas photosynthesis oxygenic lossis Anoxygenic?
Vim tias oxygen yog tsim los ntawm cov khoom lag luam thiab raug tso tawm, hom photosynthesis no hu ua oxygenic photosynthesis. Txawm li cas los xij, thaum lwm cov khoom siv txo qis ua cov khoom siv hluav taws xob, oxygen tsis tsim; Cov hom photosynthesis no hu ua anoxygenic photosynthesis.
Yuav ua li cas thiaj ua tau oxygenic photosynthesis?
Y Photosynthesis yog ntau yamkauj ruam txheej txheem uas yuav tsum tau tshav ntuj, carbon dioxide, thiab dej ua substrates. Nws tsim cov pa oxygen thiab glyceraldehyde-3-phosphate (
G3P lossis GA3P), yooj yim carbohydrate molecules uas muaj zog thiab tuaj yeem hloov mus rau hauv qabzib, sucrose, lossis lwm yam qab zib molecules.
