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).

Kev tsis ncaj ncees nyob qhov twg yog qhov hem rau kev ncaj ncees nyob txhua qhov chaw?
Martin Luther King tau hais tias: “Kev tsis ncaj ncees nyob txhua qhov chaw yog kev hem thawj rau kev ncaj ncees nyob txhua qhov chaw. Peb raug ntes nyob rau hauv ib tug inescapable network ntawm kev sib nrig sib pab, khi nyob rau hauv ib lub tsoos tsho ntawm txoj hmoo.
Cov piv txwv ntawm oxygenic photosynthesis yog dab tsi?
In cov nroj tsuag, algae thiab cyanobacteria, photosynthesis tso pa tawm. Qhov no hu ua oxygenic photosynthesis. Txawm hais tias muaj qee qhov sib txawv ntawm oxygenic photosynthesis hauv cov nroj tsuag, algae, thiab cyanobacteria, tag nrho cov txheej txheem zoo sib xws hauv cov kab mob no.
Puas yog qhov oxygenic photosynthesis?
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?
Lub sijhawm oxygenic photosynthesis lub o2 uas tso tawm los ntawm?
Puas yog tag nrho O2 tsim thaum lub sij hawm oxygenic photosynthesis tuaj ntawm?Vim li cas dej thiaj li tshwm sim ntawm ob sab ntawm qhov sib npaug ntawm cov pa oxygenic photosynthesis: … Cov dej tshwm ntawm ob sab ntawm qhov sib npaug vim tias nws yog ob qho tib si siv los ua cov reactant thiab tso tawm raws li cov khoom lag luam.
Ob theem ntawm photosynthesis nyob qhov twg?
Cov tshuaj tiv thaiv lub teeb nyob ntawm qhov chaw thylakoid daim nyias nyias hauv granum (pawg ntawm thylakoids), nyob rau hauv chloroplast. Ob theem ntawm photosynthesis: Photosynthesis yuav siv sij hawm qhov chaw nyob rau hauv ob theem: lub teeb-dependent kev tshwm sim thiab Calvin voj voog (lub teeb-yeeb yam kev xav).
