A thylakoid yog ib daim ntawv zoo li daim nyias nyias -bound qauv uas yog qhov chaw ntawm lub teeb-dependent photosynthesis Cov tshuaj tiv thaiv hauv chloroplasts thiab cyanobacteria. Nws yog qhov chaw uas muaj cov chlorophyll siv los nqus lub teeb thiab siv rau cov tshuaj biochemical.
Ib yam li ntawd, kev ua haujlwm ntawm thylakoid membrane yog dab tsi?
Lub thylakoid daim nyias nyias ntawm ib tug chloroplast yog ib qho system ntawm interconnected daim nyias nyias, uas nqa tawm lub teeb pom kev zoo. photosynthesis . Lawv tau npaj rau hauv pawg thiab tsis sib koom ua ke hu ua grana thiab stroma thylakoids, raws li, uas yog sib txawv ntawm cov txheej txheem photosystem I thiab II complexes.
Kuj Paub, dab tsi txheej txheem ntawm photosynthesis tshwm sim hauv thylakoid daim nyias nyias? Ob theem ntawm photosynthesis Siv qhov chaw hauv chloroplasts. Lub teeb tshwm sim tshwm sim nyob rau hauv lub thylakoid daim nyias nyias , thiab Calvin lub voj voog siv qhov chaw hauv stroma. Cov tshuaj tiv thaiv lub teeb ntes lub zog los ntawm lub hnub ci, uas lawv hloov mus rau tshuaj lom neeg lub zog uas khaws cia hauv cov molecules ntawm NADPH thiab ATP.
Tsuas yog li ntawd, cov membranes tseem ceeb hauv photosynthesis li cas?
Photosynthesis tshwm sim hauv chloroplasts qhov twg photosynthetic daim nyias nyias , lub thiaj li hu ua thylakoids nyob. Lawv yog lub luag haujlwm rau lub teeb pom kev zoo uas lub teeb raug ntes thiab nws lub zog hloov mus rau cov tshuaj siv zog hauv daim ntawv ntawm ATP thiab NADPH concomitant nrog kev loj hlob ntawm oxygen.
Dab tsi yog Thylakoids thiab lawv txoj haujlwm hauv photosynthesis quizlet?
Ib tug flattened, membranous hnab nyob rau hauv ib tug chloroplast. Thylakoids feem ntau muaj nyob rau hauv pawg hu ua grana uas yog interconnected; lawv membranes muaj molecular "tshuab" siv los hloov lub teeb lub zog rau tshuaj zog.

Lub luag haujlwm ntawm lub teeb hauv photosynthesis yog dab tsi?
Cov txheej txheem ntawm photosynthesis tshwm sim thaum cov nroj tsuag ntsuab siv lub zog ntawm lub teeb los hloov carbon dioxide (CO2) thiab dej (H2O) rau hauv carbohydrates. Lub teeb lub zog yog absorbed los ntawm chlorophyll, ib tug photosynthetic pigment ntawm cov nroj tsuag, thaum huab cua uas muaj carbon dioxide thiab oxygen nkag mus rau hauv cov nroj tsuag los ntawm nplooj stomata
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
Lub luag haujlwm ntawm lub teeb siv hauv photosynthesis yog dab tsi?
Light Intensity: Ib qho kev siv lub teeb ntau ntxiv ua rau muaj qhov siab ntawm photosynthesis thiab lub teeb qis qis yuav txhais tau tias tsawg npaum li cas ntawm photosynthesis. Concentration ntawm CO2: siab dua carbon dioxide concentration nce tus nqi ntawm photosynthesis. Dej: Dej yog qhov tseem ceeb rau photosynthesis
Lub luag haujlwm ntawm lub cell membrane yog dab tsi thaum lub sijhawm thauj mus los?
Lub cell membrane yog xaiv permeable rau ions thiab organic molecules thiab tswj kev txav ntawm cov khoom hauv thiab tawm ntawm lub hlwb. Lub luag haujlwm tseem ceeb ntawm cov cell membrane yog los tiv thaiv lub cell ntawm nws ib puag ncig. Nws muaj phospholipid bilayer nrog embedded proteins
Lub luag haujlwm tseem ceeb ntawm lub teeb pom kev ntawm photosynthesis yog dab tsi?
Lub luag haujlwm tag nrho ntawm cov tshuaj tiv thaiv lub teeb, thawj theem ntawm photosynthesis, yog hloov lub hnub ci zog rau hauv cov tshuaj siv hluav taws xob nyob rau hauv daim ntawv ntawm NADPH thiab ATP, uas yog siv nyob rau hauv lub teeb-yooj yim tshuaj tiv thaiv thiab roj sib sau ua ke ntawm qab zib molecules
