Rubisco tuaj yeem khi rau carbon dioxide lossis oxygen nyob ntawm ib puag ncig. Kev khi rau cov pa roj carbon dioxide thiab pib ntawm Clavin lub voj voog yog nyiam ntawm qhov kub thiab txias thiab qhov sib piv ntawm carbon dioxide-rau-oxygen.
RuBisCO khi nrog dab tsi?
Rubisco siv cov pa roj carbon dioxide thiab txuas mus rau ribulose bisphosphate, cov suab thaj luv luv nrog tsib carbon atoms. Rubisco ces muab cov saw txuas ntev mus rau hauv ob daim phosphoglycerate zoo ib yam, txhua tus muaj peb cov pa roj carbon atoms.
Lub luag haujlwm ntawm RuBisCO yog dab tsi hauv photorespiration?
In photorespiration, RuBisCO catalyses oxygenation ntawm RuBP rau ib qho molecule ntawm PGA thiab phosphoglycolate … Serine txav rov qab mus rau peroxisome, qhov chaw uas nws deaminated rau glycerate, uas dhau mus rau chloroplast rau cov synthesis ntawm photosynthetic khoom thiab photorespiration, yog li ua tiav lub voj voog.
RuBP ua li cas nrog rau hauv photorespiration?
Thawj kauj ruam ntawm kev ua pa yog oxygenation. Nws yog catalyzed los ntawm RUBISCO thiab converts RUBP rau ib molecule fo 3PGA thiab ib molecule ntawm 2PG, uas yog ib tug 2 carbon compound nrog ib pawg phosphate. Cov tshuaj tiv thaiv oxygenation yog cuam tshuam los ntawm ib puag ncig yam.
Kev sib raug zoo ntawm RuBisCO thiab photorespiration yog dab tsi?
Photorespiration (tseem hu ua oxidative photosynthetic carbon cycle, lossis C 2photosynthesis) yog hais txog cov txheej txheem hauv cov nroj tsuag metabolism uas enzyme RuBisCO oxygenates RuBP, nkim. Qee lub zog tsim los ntawm photosynthesis.
