Thaum tus txheej txheem ntawm kev rov ua dua, ntau cov neurotransmitters raug xa rov qab mus rau presynaptic neuron.
Dab tsi tshwm sim ntau dhau neurotransmitters?
Thaum lub teeb liab raug xa tawm, ntau tshaj neurotransmitters hauv synapse drift tam sim ntawd, tau tawg mus rau hauv cov khoom tsis muaj zog, los yog reabsorbed hauv cov txheej txheem hu ua reuptake. Reuptake koom nrog cov neurotransmitter raug xa rov qab mus rau hauv cov neuron uas tso tawm nws, txhawm rau tshem tawm cov synapse.
Yuav ua li cas tom qab rov siv cov tshuaj neurotransmitters?
Reuptake: tag nrho cov neurotransmitter molecule yog coj rov qab rau hauv lub davhlau ya nyob twg uas tso tawm nws. Qhov no yog ib qho kev ua ntawm norepinephrine, dopamine thiab serotonin raug tso tseg… cov neurotransmitters no raug tshem tawm ntawm lub synaptic cleft yog li lawv tsis tuaj yeem khi rau receptors.
Ob yam dab tsi tuaj yeem tshwm sim rau ntau tshaj neurotransmitters tom qab neuron reacts reuptake?
Kev rov ua dua yog dab tsi? Yuav ua li cas lwm yam ob yam yuav tshwm sim rau ntau tshaj neurotransmitters tom qab ib tug neuron reacts? Reuptake tshwm sim thaum ntau tshaj cov neurotransmitters reabsorbed los ntawm xa neuron. (Lawv tuaj yeem txav deb lossis tawg los ntawm cov enzymes.)
Tus txheej txheem hu ua dab tsi thaum cov tshuaj neurotransmitters ntxiv tau rov ua dua?
Reuptake yog qhov tseem ceeb ntawm cov txheej txheem los rov siv cov tshuaj neurotransmitters uas cov txheej txheem nquag muaj nyob rau hauv paj hlwbterminals los reabsorb lub tso tawm neurotransmitter.

Thaum tus txheej txheem ntawm electrolytic refining tooj liab?
Hauv Electrolytic refining, cov hlau tsis huv yog tsim los ua ib qho anode. … Lawv muab tso rau hauv lub da dej uas tsim nyog electrolytic uas muaj cov ntsev soluble ntawm tib cov hlau. Cov hlau yooj yim dua tseem nyob hauv cov tshuaj thiab qhov tsawg dua qhov yooj yim mus rau cov av nkos anode.
Dab tsi yog qhov ntau tshaj ntawm cov txheej txheem?
noun. agen·dum | \ ə-ˈjen-dəm \ plural agenda\ ə-ˈjen-də \ or agendums. Daim Ntawv Teev Npe txhais li cas? noun, plural a·gen·da [uh-jen-duh], a·gen·dums. ib agenda. ib yam uas yuav tsum tau ua. ib yam khoom ntawm cov txheej txheem.

Lub neej muaj txheej txheem ntawm lub ntiaj teb yog the Biosphere. Lub neej muaj dabtsi? Cov kabmob lub neej yog qhov tseem ceeb ntawm lub sijhawm ntev ntawm cov kabmob tuaj yeem xav tau ua raws li qhov xav tau hauv kev ua haujlwm ua ntej tau teev tseg.
Cov txheej txheem huab cua twg muaj txheej txheej ozone?
Feem ntau atmospheric ozone yog concentrated nyob rau hauv ib txheej nyob rau hauv the stratosphere, li ntawm 9 txog 18 mais (15 mus rau 30 km) saum lub ntiaj teb nto (saib daim duab hauv qab). Ozone yog ib qho molecule uas muaj peb lub atoms oxygen.
Rau cov txheej txheem lossis cov txheej txheem?
Cov txheej txheem yog feem ntau yog ntau lub npe hais txog cov qauv uas tuaj yeem txiav txim siab. Nws cov lus yog cov qauv, tab sis cov pov thawj qhia tau tias cov txheej txheem feem ntau raug siv los ua cov lus thiab ntau ntau, zoo li cov ntaub ntawv thiab cov txheej txheem thiab lawv cov lus siv tsawg dua cov ntaub ntawv thiab cov txheej txheem.
