Enzymes yog tsim los ntawm cov amino acids, thiab lawv yog cov proteins. Thaum ib enzyme yog tsim, nws yog tsim los ntawm stringing ua ke ntawm 100 thiab 1,000 amino acids nyob rau hauv ib tug heev tshwj xeeb thiab tshwj xeeb kev txiav txim. Cov saw ntawm cov amino acids ces folds mus rau hauv ib tug tshwj xeeb zoo.
Tsis tas li ntawd, cov enzymes ua 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 ua hauj lwm ntau yam tseem ceeb hauv lub cev, xws li pab digestion thiab metabolism.
Tom qab, lo lus nug yog, dab tsi yog qhov enzyme yooj yim txhais? Enzymes yog protein molecules nyob rau hauv cov hlwb uas ua hauj lwm raws li lom catalysts. Enzymes ceev cov tshuaj tiv thaiv hauv lub cev, tab sis tsis txhob siv rau hauv cov txheej txheem, yog li siv tau ntau dua. Yuav luag tag nrho cov tshuaj biochemical hauv cov khoom muaj sia xav tau cov enzymes.
Ib tug kuj yuav nug, dab tsi yog piv txwv ntawm ib qho enzyme?
Ib cov enzymes Lub npe feem ntau muab los ntawm nws cov substrate los yog cov tshuaj tiv thaiv nws catalyzes, nrog lo lus xaus hauv -ase. Piv txwv yog lactase, cawv dehydrogenase thiab DNA polymerase. txawv cov enzymes uas catalyze tib cov tshuaj tiv thaiv yog hu ua isozymes.
Puas yog cov enzymes xav tau rau cov metabolism?
Enzymes yog qhov tseem ceeb rau metabolism vim hais tias lawv tso cai rau cov kab mob los tsav cov kev xav tau uas xav tau lub zog uas yuav tsis tshwm sim los ntawm lawv tus kheej, los ntawm kev sib txuas lawv mus rau qhov tshwm sim uas tso tawm lub zog.

Dab tsi yog siv los tso cai rau ammeter los ntsuas qhov sib txawv?
Ammeters ntsuas hluav taws xob tam sim no Hauv ammeter tsim, cov khoom siv sab nraud ntxiv los txuas ntxiv qhov siv tau ntawm qhov kev txav mus los txuas nrog kev sib txuas nrog kev txav mus los tsis yog nyob rau hauv series raws li cov ntaub ntawv rau voltmeters
Dab tsi yog cov hlau nplaum uas ua los ntawm qhov kev npaj ntawm electrons yog dab tsi?
Electrons yog teem rau hauv plhaub thiab orbitals nyob rau hauv ib tug atom. Yog hais tias lawv sau lub orbitals kom muaj ntau spin taw tes rau hauv qab (los yog vice versa), txhua atom yuav ua zoo li ib tug me me hlau nplaum. Thaum ib daim ntawm cov hlau tsis muaj hlau nplaum (lossis lwm yam khoom siv ferromagnetic) raug rau sab nraud magnetic teb, ob yam tshwm sim
Dab tsi yog kev siv cov saw hlau nuclear siv rau?
Nuclear chain reaction. Nuclear chain reactions yog cov tshuaj tiv thaiv uas tau txais lub zog nuclear, feem ntau los ntawm nuclear fission. Cov kev cuam tshuam ntawm cov saw hlau no yog qhov muab cov chaw tsim hluav taws xob nuclear nrog lub zog uas tom qab ntawd hloov mus ua hluav taws xob siv los ntawm tib neeg
Dab tsi yog qhov sib npaug siv los xam tag nrho cov khoom siv hluav taws xob siv?
Cov mis uas txuas lub zog thiab lub zog yog: Zog = Lub Zog x Sijhawm. Chav tsev ntawm lub zog yog joule, lub zog ntawm lub zog yog watt, thiab chav tsev ntawm lub sijhawm yog qhov thib ob
Dab tsi yog qhov txawv ntawm cov khoom siv organic thiab cov khoom siv organic?
Dab tsi yog qhov txawv ntawm cov khoom siv organic thiab organic teeb meem? Organic khoom yog txhua yam uas tseem muaj sia nyob thiab tam sim no nyob rau hauv lossis hauv av. Rau nws los ua cov organic teeb meem, nws yuav tsum tau decomposed rau hauv humus. Humus yog cov khoom siv organic uas tau hloov dua siab tshiab los ntawm cov kab mob mus rau lub xeev tsis muaj zog
