Zoo li tag nrho cov proteins, enzymes yog tsim los ntawm hlua ntawm cov amino acids chemically bonded rau ib leeg. Cov ntawv cog lus no muab txhua lub enzyme ib tus qauv tshwj xeeb, uas txiav txim siab nws txoj haujlwm.
YPuas yog ib qho enzyme ib qho protein?
Enzymes yog proteins, thiab lawv ua rau cov tshuaj tiv thaiv kab mob biochemical ntau dua los ntawm kev txo qis lub zog ua kom muaj zog ntawm cov tshuaj tiv thaiv, yog li ua rau cov tshuaj tiv thaiv no mus ntau txhiab lossis ntau lab lub sijhawm sai dua. tshaj lawv yuav tsis muaj catalyst. Enzymes tshwj xeeb rau lawv cov substrates.
Dab tsi yog cov enzymes ua los ntawm thiab lawv ua dab tsi?
Enzymes yog tsim los ntawm cov saw ntev ntawm cov amino acids uas tuav ua ke los ntawm peptide bonds. Enzymes pab nrog cov txheej txheem xws li kev zom zaub mov, ntshav txhaws, thiab tsim cov tshuaj hormone. Lawv yeej yog catalyze (ua rau) lossis ua kom cov tshuaj lom neeg muaj zog uas tshwm sim hauv lub cev ntawm cov khoom muaj sia.
enzymes ua los ntawm dab tsi?
Yuav luag tag nrho cov enzymes yog proteins, ua los ntawm cov saw hlau ntawm cov amino acids, thiab lawv ua haujlwm tseem ceeb ntawm kev txo qis kev ua kom muaj zog ntawm cov tshuaj tiv thaiv hauv lub cell.
Dab tsi yog cov enzymes feem ntau ua los ntawm?
Structurally, feem ntau ntawm cov enzymes yog proteins. Tsis tas li RNA molecules muaj cov haujlwm catalytic (ribozymes). Coenzymes yog cov khoom me me uas tsis muaj protein ntau uas cuam tshuam rau qee cov enzymes.

Puas yog cov dab dab dab dab dab dab dab dab dab dab dab dab?
Myth: Ib tug dab tshos tsis yog neeg ncaj ncees yog tiasnws haum yog. Fact: Tu siab, qhov no yog ib lo lus tsis tseeb uas tau raug perpetuated los ntawm aversive trainers. Txawm hais tias haum rau lub caj dab kom zoo khawb rau hauv cov tawv nqaij rhiab nyob ib ncig ntawm lub caj dab, uas ua rau muaj kev puas tsuaj loj rau cov thyroid, esophagus, thiab trachea.
Dab tsi yog kev xav ntawm autonomists dab tsi yog qhov kev xav ntawm kev zoo nkauj ntawm kev coj ncaj ncees?
Kev lig kev cai, muaj ob txoj haujlwm tawm tsam kev xav txog kev coj ua raws li kev cai lij choj ntawm kev ntsuas kev ncaj ncees ntawm kev kos duab: 'kev coj ncaj ncees kev ncaj ncees Ethics lossis kev coj ncaj ncees yog ib ceg ntawm kev xav uas "
Puas yog cov dab dab dab dab dab dab tau them?
OHL cov neeg ua si tsis tau nyiaj hli, vim lawv tsis raug lees paub tias yog cov neeg ua haujlwm raws li Txoj Cai Kev Ua Haujlwm. Txawm li cas los xij, lawv suav nrog cov txiaj ntsig xws li nyiaj rov qab txhua xyoo, tag nrho cov nqi kawm ntawv them, thiab daim pib pub dawb.
Dab tsi yog qhov ceev ntawm cov hlau raug tshem tawm los ntawm lub cuab yeej ntawm lub workpiece?
1. Kev nrawm . Kev txiav ceev (v) ntawm ib lub cuab yeej yog qhov ceev uas cov hlau raug tshem tawm los ntawm lub cuab yeej ntawm lub workpiece. Nyob rau hauv ib lub tshuab dhos, nws yog lub peripheral ceev ntawm kev ua hauj lwm yav dhau los cov cuab yeej txiav qhia nyob rau hauv meters ib feeb.
Los ntawm qhov kev txiav txim ntawm enzymes tus nqi ntawm cov tshuaj tiv thaiv biochemical?
Enzymes yog cov khoom siv roj ntsha. Catalysts txo qis lub zog ua kom muaj zog rau cov tshuaj tiv thaiv. Qhov qis dua lub zog ua kom muaj zog rau cov tshuaj tiv thaiv, qhov nrawm dua. Yog li enzymes nrawm cov tshuaj tiv thaiv los ntawm kev ua kom lub zog qis.
