Cov tshuaj tiv thaiv ntawm RUBISCO nrog cov pa oxygen thiab cov txheej txheem metabolic ntawm qhov tshwm sim 2-PG yog hu ua "photorespiration". Nws yog hu ua qhov no vim hais tias nws tsuas tshwm sim nyob rau hauv lub teeb (mitochondrial respiration tseem nyob rau hauv qhov tsaus ntuj) thiab vim hais tias nws siv oxygen thiab tsim carbon dioxide, ib yam li mitochondrial respiration.
Rubisco koom nrog dab tsi?
Ribulose-1, 5-bisphosphate carboxylase-oxygenase, feem ntau paub los ntawm cov ntawv luv luv RuBisCo, rubisco, RuBPCase, lossis RuBPco, yog ib qho enzyme koom nrog thawj kauj ruam tseem ceeb ntawm kev txhim kho carbon, cov txheej txheem uas atmospheric carbon dioxide hloov los ntawm cov nroj tsuag thiab lwm yam kab mob photosynthetic mus rau lub zog-nplua nuj molecules …
YPuas Rubisco hauv photosynthesis thiab cellular respiration?
Tshwj xeeb, RuBisCO catalyzes tawm tsam ntawm carbon dioxide thiab RuBP thaum pib lub voj voog. … Cov kev cuam tshuam ntawm kev ua pa yog nqus cov suab thaj thiab siv cov pa oxygen los ua kom cov pa roj carbon dioxide thiab dej, tso lub zog. Yog li, cov reactants ntawm photosynthesis yog cov khoom ua pa, thiab vice versa.
Lub luag haujlwm ntawm Rubisco yog dab tsi?
Lub enzyme ribulose 1, 5-bisphosphate carboxylase (Rubisco) catalyses cov pa roj carbon dioxide nkag mus rau hauv photosynthetic metabolism, muab cov molecules txais uas noj cov khoom ntawm lub teeb pom kev ntawm photosynthesis, thiab tswj cov pas dej ntau qhov ntawm qhov tseem ceeb photosynthetic intermediates.
Lub luag haujlwm ntawm Rubisco hauv Photorespiration yog dab tsi?
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.
