Photorespiration yog pib los ntawm kev ua haujlwm ntawm oxygenase ribulose-1 , 5-bisphosphate-carboxylase/oxygenase ( RUBISCO ), tib enzyme uas tseem muaj lub luag haujlwm rau CO2 fixation yuav luag tag nrho cov kab mob photosynthetic.
Tsis tas li ntawd, lub ntsiab enzyme twg koom nrog hauv Calvin lub voj voog Nws cuam tshuam li cas rau Photorespiration?
Cov enzyme, rubisco , tsis tsuas yog pib kho cov pa roj carbon monoxide hauv Calvin lub voj voog; nws kuj ua ke nrog oxygen los pib photorespiration. Raws li nws lub npe qhia (rubsiCO) enzyme yog ob qho tib si carboxylase thiab oxygenase.
Ib tug kuj yuav nug, dab tsi ua rau Photorespiration? Photorespiration yog ib txoj hauv kev pov tseg uas tshwm sim thaum Calvin lub voj voog enzyme rubisco ua rau oxygen es tsis yog carbon dioxide. Crassulacean acid metabolism (CAM) cov nroj tsuag txo qis photorespiration thiab txuag dej los ntawm kev sib cais cov kauj ruam hauv lub sijhawm, nruab nrab ntawm hmo ntuj thiab nruab hnub.
Raws li txoj cai, lub luag haujlwm ntawm photorespiration hauv cov nroj tsuag yog dab tsi?
Photorespiration (tseem hu ua oxidative photosynthetic carbon cycle, los yog C2 photosynthesis) hais txog cov txheej txheem hauv cog metabolism qhov twg enzyme RuBisCO oxygenates RuBP, nkim qee lub zog tsim los ntawm photosynthesis.
Dab tsi o2 thiab co2 mob txhawb nqa Photorespiration?
Kev khi rau carbon dioxide thiab pib ntawm Clavin lub voj voog yog nyiam ntawm qhov kub thiab txias carbon dioxide -rau- oxygen piv. Kev khi rau oxygen thiab pib ntawm photorespiration yog nyiam ntawm qhov kub thiab txias carbon dioxide -rau- oxygen piv.

Lub luag haujlwm ntawm CDK yog dab tsi hauv lub cev ua haujlwm ntawm tes tshwj xeeb hauv lub voj voog ntawm tes?
Los ntawm phosphorylation, Cdks teeb liab lub xov tooj ntawm tes uas nws tau npaj kom dhau mus rau theem tom ntej ntawm lub voj voog ntawm tes. Raws li lawv lub npe qhia, Cyclin-Dependent Protein Kinases yog nyob ntawm cyclins, lwm chav kawm ntawm kev tswj hwm cov protein. Cyclins khi rau Cdks, ua kom cov Cdks rau phosphorylate lwm cov molecules
Dab tsi yog qhov txawv ntawm Marine West Coast huab cua thiab dab tsi yog lub luag haujlwm rau cov yam ntxwv ntawd?
Cov ntsiab lus ntawm Marine West Coast Qhov kev nyab xeeb ntawm cov yam ntxwv tseem ceeb yog lub caij ntuj sov me me thiab lub caij ntuj no thiab cov nag lossis daus txhua xyoo. Qhov ecosystem no muaj kev cuam tshuam loj heev los ntawm nws qhov ze rau ntawm ntug dej hiav txwv thiab roob. Nws yog qee zaum hu ua huab cua sab hnub poob ntug dej hiav txwv lossis dej hiav txwv huab cua
Lub organelle twg yog lub luag haujlwm rau lub zog tshuaj uas xav tau rau lub cell ua haujlwm?
Mitochondria Function Mitochondria feem ntau hu ua "powerhouses" lossis "zog factories" ntawm lub xovtooj vim tias lawv yog lub luag haujlwm rau kev ua adenosine triphosphate (ATP), lub xovtooj ntawm lub zog nqa lub cev
Lub luag haujlwm ntawm enzyme yog dab tsi?
Enzymes yog cov roj ntsha molecules (feem ntau yog cov proteins) uas ua rau kom nce tus nqi ntawm txhua yam tshuaj lom neeg uas tshwm sim hauv cov hlwb. Lawv yog ib qho tseem ceeb rau lub neej thiab pab ntau yam haujlwm tseem ceeb hauv lub cev, xws li pab digestion thiab metabolism
Cov txheej txheem dab tsi yog lub luag haujlwm rau txoj haujlwm ua haujlwm sib txawv?
Position-effect variegation (PEV) tshwm sim thaum cov noob ib txwm nyob hauv euchromatin yog sib xyaw nrog heterochromatin los ntawm kev hloov kho lossis hloov pauv. Thaum lub ntim ntim heterochromatin kis thoob plaws heterochromatin / euchromatin ciam teb, nws ua rau kev hloov pauv ntawm kev ntsiag to hauv tus qauv stochastic
