Ethylene . (Science: Tshuaj tsob nroj biology ) cog kev loj hlob tshuaj (phytohormone, nroj tsuag hormone), koom nrog txhawb kev loj hlob, epinasty, txiv hmab txiv ntoo ripening, senescence thiab tawg ntawm dormancy. Nws qhov kev ua tau zoo txuas nrog cov auxin.
Hais txog qhov no, ethylene yog dab tsi thiab nws txoj haujlwm?
Ethylene ua haujlwm raws li cov tshuaj hormones hauv cov nroj tsuag. Nws ua nyob rau hauv cov kab nyob thoob plaws tus lub neej ntawm tus cog los ntawm stimulating los yog regulating tus ripening ntawm txiv hmab txiv ntoo, tus qhib paj, thiab tus abscission (los yog shedding) ntawm nplooj.
Tsis tas li ntawd, ethylene tsim nyob rau hauv cov nroj tsuag li cas? Ethylene yog tsim tawm nyob rau hauv tag nrho cov siab nroj tsuag thiab yog tsim tawm los ntawm methionine nyob rau hauv tag nrho cov ntaub so ntswg. ATP thiab dej ntxiv rau methionine ua rau poob ntawm peb phosphates thiab S-adenosyl methionine. 1-amino-cyclopropane-1-carboxylic acid synthase (ACC-synthase) pab txhawb rau ntau lawm ACC los ntawm SAM.
Hauv qhov no, ethylene botany yog dab tsi?
Ethylene . Ethylene yog ib pawg ntawm cov nroj tsuag kev loj hlob regulators uas yog dav siv rau ripening txiv hmab txiv ntoo thiab rau zus tau tej cov paj ntau thiab txiv hmab txiv ntoo. Ntxiv mus, ethylene Nws kuj yog siv nyob rau hauv kev ua liaj ua teb ua liaj ua teb rau ripen txiv hmab txiv ntoo, germination ntawm noob, thiab lwm yam.
ethylene yog tsim los ntawm dab tsi?
Ethylene yog tsim tawm kev lag luam los ntawm chav tawg ntawm ntau yam ntawm hydrocarbon feedstocks. Hauv Tebchaws Europe thiab Asia, ethylene yog tau mas los ntawm cracking naphtha, gasoil thiab condensates nrog coproduction ntawm propylene, C4 olefins thiab aromatics (pyrolysis roj av).

Dab tsi yog qhov kev tawm tswv yim zoo hauv biology?
Kev tawm tswv yim zoo yog ib txoj hauv kev uas cov khoom kawg ntawm qhov kev txiav txim ua rau ntau qhov kev txiav txim tshwm sim hauv cov lus tawm tswv yim. Nws yog qhov sib txawv nrog cov lus tawm tswv yim tsis zoo, uas yog thaum kawg ntawm qhov kev txiav txim txwv tsis pub qhov kev txiav txim txuas ntxiv mus. Cov txheej txheem no muaj nyob hauv ntau lub tshuab lom neeg
Dab tsi yog proteasome hauv biology?
Proteasome: Ib qho protein degradation 'tshuab' nyob rau hauv lub cell uas zom tau ntau yam proteins rau hauv luv polypeptides thiab amino acids. Proteasome yog nws tus kheej tsim los ntawm cov proteins. Nws yuav tsum tau ATP ua haujlwm. Tib neeg lub cell muaj txog 30,000 proteasomes
GPP hauv biology yog dab tsi?
Kev tsim khoom tseem ceeb. Tag nrho cov khoom tsim tawm tag nrho, lossis GPP, yog tus nqi uas lub hnub ci zog tau ntes hauv cov piam thaj molecules thaum lub sijhawm photosynthesis (lub zog ntes ib cheeb tsam ntawm ib lub sijhawm). Cov neeg tsim khoom xws li cov nroj tsuag siv qee lub zog no rau cov metabolism / cellular ua pa thiab qee qhov rau kev loj hlob (tsim cov ntaub so ntswg)
Dab tsi yog mucor hauv biology?
Mucor yog ib hom kab mob pwm. Pwm yog nyob rau hauv lub nceeg vaj Fungi, thiab lawv yog tsim los ntawm xov zoo li hyphae uas kis tawm los ntawm ib tug pom mycelium. Mucor feem ntau pom nyob rau hauv av, thiab feem ntau hom loj hlob zoo tshaj plaws nyob rau hauv qis kub. Mucor indicus yog cov pwm uas muaj txiaj ntsig tiag tiag
Dab tsi yog pyruvic acid hauv biology?
Txhais. npe. Tsis muaj xim, dej-soluble, organic kua ua los ntawm kev tawg ntawm carbohydrates thiab suab thaj thaum lub sij hawm glycolysis, thiab nrog ib tug tshuaj formula ntawm: CH3COCO2H. Ntxiv. Yog tias muaj cov pa oxygen, pyruvic acid hloov mus rau acetyl coenzyme A uas nkag mus rau hauv txoj kev tsim lub zog, lub voj voog Krebs
