Lub Luag Haujlwm ntawm Organic Acids hauv C4 Photosynthesis. Organic acids muaj kev koom tes hauv ntau txoj hauv kev metabolic hauv txhua cov nroj tsuag. Malate tau lees paub tias yog tus loj organic acid Kev hloov pauv hauv NADP-malic enzyme-hom C4 hom, thaum Asp sau lub luag haujlwm no hauv NAD-malic enzyme-hom thiab phosphoenolpyruvate carboxykinase-hom nroj tsuag

Yog li ntawd, cov organic acids khaws cia nyob rau hauv cov nroj tsuag cell nyob qhov twg?

Cov organic acid yog khaws cia hauv vacuoles mus txog hnub tom qab. Thaum nruab hnub, CAM nroj tsuag tsis qhib lawv stomata, tab sis lawv tseem muaj peev xwm photosynthesize.

Ib tug kuj yuav nug, dab tsi lub luag hauj lwm yog acid ua nyob rau hauv photosynthesis? Plaub- thiab 3-C organic kua qaub yog cov substrates thiab cov khoom ntawm C4 kua qaub hloov lub voj voog uas txuas CO2 txhawb nrog CO2 fixation rau hauv carbohydrates. Hauv feem ntau C4 cov nroj tsuag, cov tshuaj tiv thaiv no tshwm sim dhau ob hom cell thiab muaj nuj nqi kom concentrate CO2 nyob rau hauv lub cev ntawm ib tug C4 nplooj.

Hauv qhov no, malate nroj tsuag yog dab tsi?

Abstract. Malate yog lub hauv paus metabolite cog cell nrog lub luag haujlwm tseem ceeb hauv cog physiology thiab metabolism. Ntawm no, peb xaus cov kev nce qib tsis ntev los no hauv peb txoj kev nkag siab ntawm malate homeostasis hauv central metabolism, tiv thaiv cell ua haujlwm, thiab hauv paus exudation.

C4 acid yog dab tsi?

Oxaloacetate (OAA), malate, thiab aspartate (Asp) yog cov substrates rau cov C4 acid Lub voj voog uas underpins CO2 concentrating mechanism ntawm C4 photosynthesis. Hauv lub voj voog no, OAA yog tam sim, luv luv, cov khoom lag luam ntawm thawj zaug CO2 fixation kauj ruam hauv C4 nplooj mesophyll hlwb.
