Qhov sib txawv tseem ceeb ntawm bacteriochlorophyll thiab chlorophyll yog qhov anoxygenic phototrophs, xws li cov kab mob ntshav, heliobacteria thiab ntsuab sulfur kab mob, thiab lwm yam. muaj bacteriochlorophylls, thaum oxygenic phototrophs xws li cov nroj tsuag ntsuab, algae thiab cyanobacteria muaj chlorophylls.
Muaj ob hom photosynthesis; oxygenic photosynthesis thiab anoxygenic photosynthesis. Kuj tseem muaj ob hom photosynthetic pigments li chlorophyll thiab bacteriochlorophyll. Oxygenic phototrophs muaj chlorophyll whereas anoxygenic phototrophs muaj bacteriochlorophyll. Bacteriochlorophyll thiab chlorophyll zoo ib yam nyob rau hauv tag nrho cov qauv. Tab sis lawv txawv nyob rau hauv kev hloov nyob ib ncig ntawm lub nplhaib thiab nyob rau hauv qhov ntev thiab hloov nyob rau hauv lub phytol tail. Muaj plaub hom chlorophylls thaum muaj xya hom bacteriochlorophylls.
YBacteriochlorophyll yog dab tsi?
Bacteriochlorophyll yog cov xim photosynthetic pom nyob rau hauv cov kab mob phototrophic xws li cov kab mob ntshav, heliobacteria thiab cov kab mob ntsuab sulfur, thiab lwm yam. Cov pigment no koom nrog anoxygenic photosynthesis. Hauv lwm lo lus, bacteriochlorophyll koom nrog hauv anoxygenic photosynthesis, uas tsis tsim oxygen. Muaj xya qhov sib txawv ntawm bacteriochlorophylls li a, b, c, d, e, cs thiab g.
Daim duab 01: Bacteriochlorophyll
Bacteriochlorophylls muaj peev xwm nqus tau lub zog ntawm lub teeb. Tag nrho cov qauv ntawm bacteriochlorophyll zoo ib yam li chlorophyll. Txawm li cas los xij, qhov sib txawv yog qhov hloov pauv nyob ib puag ncig lub nplhaib thiab qhov ntev thiab hloov pauv ntawm phytol tus Tsov tus tw. Bacteriochlorophylls ntes ntev wavelength nqus siab tshaj plaws nyob rau hauv infrared wavelength range.
YChlorophyll yog dab tsi?
Chlorophyll yog thawj xim ntawm cov kab mob photosynthetic, suav nrog cov nroj tsuag thiab algae. Nws yog xim ntsuab xim muaj peev xwm ntes lub zog ntawm lub hnub ci. Qhov tseeb, chlorophyll yog hais txog tsev neeg ntawm cov nroj tsuag pigments. Nws muaj ob peb chlorophyll pigments, tab sis chlorophyll a thiab b yog cov xim ntau.
Daim duab 02: Chlorophyll
Chlorophyll molecules yog tsim los ntawm carbon, hydrogen, nitrogen, thiab oxygen. Cov ntsiab lus no yog tsim nyob ib ncig ntawm lub hauv paus hlau ion magnesium. Chlorophylls nqus daj thiab xiav xim wavelengths los ntawm electromagnetic hluav taws xob thiab muaj kev cuam tshuam ntsuab. Yog li, qhov no yog vim li cas lawv thiaj pom ntsuab.
Dab tsi yog qhov zoo sib xws ntawm Bacteriochlorophyll thiab Chlorophyll?
- Bacteriochlorophyll thiab chlorophyll yog ob hom photosynthetic pigments.
- Lawv pom hauv photoautotrophs.
- Ob hom xim tuaj yeem ntes thiab nqus lub zog thiab tsim ATP.
- Lawv tag nrho cov qauv zoo ib yam.
- Lawv ob leeg muaj lub nplhaib sib txawv tetrapyrrole nrog Mg2+ hauv nruab nrab thiab ntev 20-carbon phytol tail.
Qhov txawv ntawm Bacteriochlorophyll thiab Chlorophyll yog dab tsi?
Bacteriochlorophyll yog cov xim photosynthetic pom nyob rau hauv cov kab mob prokaryotic photosynthetic lossis cov kab mob phototrophic. Nyob rau hauv sib piv, chlorophyll yog ib tug photosynthetic pigment pom nyob rau hauv cov nroj tsuag, algae thiab cyanobacteria. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm bacteriochlorophyll thiab chlorophyll.
Ntxiv mus, lwm qhov sib txawv tseem ceeb ntawm bacteriochlorophyll thiab chlorophyll yog tias cov bacteriochlorophylls koom nrog hauv anoxygenic photosynthesis; yog li ntawd, nws tsis tsim oxygen. Ntawm qhov tod tes, chlorophylls koom nrog oxygenic photosynthesis thiab tsim cov pa oxygen. Tsis tas li ntawd, muaj plaub hom chlorophylls thaum muaj xya hom bacteriochlorophylls.
Hauv qab infographic tabulates qhov txawv ntawm bacteriochlorophyll thiab chlorophyll.
Summary – Bacteriochlorophyll vs Chlorophyll
Bacteriochlrophyll thiab chlorophyll yog ob hom xim ntuj. Qhov tseeb, lawv yog photosynthetic pigments. Bacteriochlorophylls muaj nyob rau hauv cov kab mob phototrophic los yog anoxygenic phototrophs xws li cov kab mob ntshav, heliobacteria thiab ntsuab sulfur kab mob, thiab lwm yam. Meanwhile, chlorophylls muaj nyob rau hauv oxygenic phototrophs xws li nroj tsuag, algae thiab cyanobacteria. Tsis tas li ntawd, muaj plaub hom chlorophylls, thaum muaj xya hom bacteriochlorophylls. Yog li, qhov no yog qhov txawv ntawm bacteriochlorophyll thiab chlorophyll.
