Qhov sib txawv tseem ceeb ntawm chlorophyll A thiab B yog tias chlorophyll A yog thawj cov xim photosynthetic nyob rau hauv cov nroj tsuag thiab algae thaum chlorophyll B yog ib qho khoom siv xim uas sau lub zog thiab dhau mus rau chlorophyll A.

Chlorophyll yog tsev neeg ntawm cov xim ntuj uas muaj nyob hauv cov nroj tsuag thiab algae thiab yog lub luag haujlwm rau lawv cov xim ntsuab. Chlorophyll absorbs lub zog los ntawm lub hnub ci thiab siv lub zog no los tsim cov carbohydrates los ntawm dej thiab carbon dioxide. Nws yog cov txheej txheem hu ua photosynthesis uas txhawb nqa cov txheej txheem lub neej hauv txhua cov nroj tsuag raws li lawv cov kev xav tau ntawm lub zog tau ntsib los ntawm cov txheej txheem no. Tsis tas li ntawd, photosynthesis yog cov txheej txheem tseem ceeb uas txhawb nqa tag nrho cov kab mob uas muaj sia nyob vim tias cov nroj tsuag yog thawj cov neeg tsim khoom ntawm tag nrho cov khoom noj. Tsiaj txhu thiab tib neeg noj cov khoom ntawm cov nroj tsuag. Hauv tsev neeg chlorophyll pigment, muaj ntau hom chlorophyll pigments. Ntawm lawv, chlorophyll A thiab chlorophyll B yog ob hom chlorophylls. Lawv muaj cov qauv zoo sib xws nrog qhov sib txawv me ntsis ntawm lub nplhaib porphyrin. Chlorophyll A muaj CH3 pawg hauv lub nplhaib porphyrin thaum chlorophyll B muaj CHO (aldehyde pawg) hauv lub nplhaib porphyrin.

Chlorophyll A yog dab tsi?

Chlorophyll A yog thawj cov xim photosynthetic muaj nyob hauv cov nroj tsuag thiab algae. Nws yog hom kev faib tawm ntau tshaj plaws ntawm chlorophylls. Nws yog xim ntsuab xim xim, uas tuaj yeem ntes lub zog ntawm lub hnub ci thiab tsim cov khoom noj hauv photoautotrophs. Muaj ob hom photosystems uas cuam tshuam nrog lub teeb pom kev zoo.

Daim duab 01: Chlorophyll A

Nyob rau hauv ob lub photosystems, cov tshuaj tiv thaiv chaw muaj chlorophyll A molecules. Lawv nqus liab, xiav thiab violet wavelengths thiab qhia txog ntsuab xim tawm. Thaum xav txog cov qauv, nws muaj lub nplhaib porphyrin zoo ib yam li chlorophyll B. Txawm li cas los xij, lub nplhaib porphyrin ntawm chlorophyll A muaj CH3 pawg sab.

Chlorophyll B yog dab tsi?

Chlorophyll B yog ib qho khoom siv photosynthetic pigment muaj nyob rau hauv cov nroj tsuag thiab ntsuab algae. Nws pab chlorophyll A los ntawm kev sau lub zog thiab dhau mus rau nws. Zoo ib yam li chlorophyll A, nws yog xim ntsuab xim. Tsis tas li ntawd, nws muaj cov qauv zoo ib yam li cov chlorophyll A.

Daim duab 02: Chlorophyll B

Txawm li cas los xij, nws lub nplhaib porphyrin muaj ib pawg CHO, uas tsis muaj nyob rau hauv chlorophyll A. Cov xim molecules no ua lub teeb-txiav kav hlau txais xov ntawm photosystem I. Piv rau chlorophyll A, chlorophyll B yog tsawg dua. Tsis tas li ntawd, chlorophyll B yog soluble nyob rau hauv polar solvents ntau dua li chlorophyll A. Nws feem ntau absorbs xiav lub teeb.

Dab tsi yog qhov zoo sib xws ntawm Chlorophyll A thiab B?

  • Chlorophyll A thiab B yog ob hom chlorophylls uas yog xim ntsuab xim.
  • Ob leeg koom nrog hauv photosynthesis.
  • Tsis tas li, ob leeg muaj peev xwm nqus tau lub zog los ntawm tshav ntuj.
  • Tsis tas li ntawd, ob qho tib si muaj nyob rau hauv cov kab mob photosynthetic, tshwj xeeb tshaj yog nyob rau hauv cov nroj tsuag ntsuab thiab algae.
  • Dhau li ntawd, ob qho tib si lawv cov qauv muaj lub nplhaib porphyrin.
  • Thiab, ob qho tib si ntawm lawv yog photoreceptors hauv kev nkag siab tias lawv tuaj yeem siv lub hnub ci los ua zaub mov rau cov nroj tsuag.

Qhov txawv ntawm Chlorophyll A thiab B yog dab tsi?

Chlorophyll A yog ntau tshaj plaws thoob ntiaj teb hom xim ntsuab chlorophyll xim muaj nyob hauv cov nroj tsuag, algae thiab cyanobacteria. Yog li, nws yog thawj photosynthetic pigment uas absorbs lub teeb los ntawm liab, xiav thiab violet wavelengths thiab qhia ntsuab. Ib yam li ntawd, chlorophyll A yog tam sim no nyob rau hauv cov tshuaj tiv thaiv chaw ntawm ob lub photosystems. Ntawm qhov tod tes, chlorophyll B yog ib qho khoom siv pigment uas khaws lub zog thiab xa mus rau chlorophyll A. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm chlorophyll A thiab B.

Tsis tas li, muaj qhov sib txawv ntawm chlorophyll A thiab B hauv lawv cov qauv. Chlorophyll A muaj CH3 pawg sab txuas nrog lub nplhaib porphyrin thaum chlorophyll B muaj CHO pawg txuas nrog lub nplhaib porphyrin. Cov lus piav qhia ntxiv txog qhov sib txawv ntawm chlorophyll A thiab B yog muab rau hauv cov ntawv hauv qab no.

Summary – Chlorophyll A vs B

Hauv luv luv, Chlorophyll A thiab B yog ob hom xim ntsuab xim ntawm chlorophyll tsev neeg. Chlorophyll A yog thawj cov xim photosynthetic thaum chlorophyll B yog cov xim ntxiv. Ntawm qhov tod tes, Chlorophyll B sau lub zog thiab dhau mus rau chlorophyll A kom zoo siab. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm chlorophyll A thiab B. Tsis tas li ntawd, lawv muaj qhov sib txawv me me hauv lawv cov qauv xws li chlorophyll B muaj ib pawg aldehyde txuas nrog porphyrin nplhaib tsis zoo li hauv chlorophyll A.
