Boiling thiab Denaturation
Thaum kub ib puag ncig boiling , cov tshuaj sib txuas uas tuav ua ke cov qauv ntawm cov enzymes pib tawg. Qhov tshwm sim poob ntawm cov qauv peb-seem ua rau cov enzymes kom tsis haum lawv lub hom phiaj substrate molecules, thiab cov enzymes tag nrho tsis ua haujlwm.
Ib yam li ntawd, nws tau nug, dab tsi yog qhov cuam tshuam ntawm kev rhaub dej ntawm cov haujlwm enzyme?
Piav qhia: Ib enzyme yog ib tug protein molecule nrog ib tug ruaj 3-dimensional zoo uas yog tuav nyob rau hauv qhov chaw los ntawm ionic bonds, hydrogen bonds thiab lwm yam. Txawm li cas los xij, vim boiling cov bonds yuav tawg thiab tertiary qauv ntawm lub enzyme yuav ploj thiab nws yuav tsis tuaj yeem tsim ib qho enzyme - substrate complex los tsim cov khoom.
Kuj Paub, yuav ua li cas thaum pepsin boiled? Enzymes yog cov protein ntau uas txhawb cov tshuaj lom neeg. Qhov ntawd txhais tau tias lawv pab tsim lossis cuam tshuam ntawm cov ntawv cog lus atomic. Enzymes, zoo li lwm cov protein, tau txais lawv cov khoom los ntawm lawv cov duab. Txhua yam uas cuam tshuam cov duab ntawm cov enzyme - suav nrog boiling thiab khov - yuav ua rau nws tsis ua haujlwm.
Tsuas yog li ntawd, puas enzymes tuag thaum rhuab?
Kub: Ua kom sov ntxiv yuav ua kom nrawm ntawm qhov tsis sib haum xeeb ntawm cov tshuaj tsis haum, thiab yog li qhov kub nce nrawm dua enzyme mediated kev xav, tab sis tsuas yog mus rau ib lub ntsiab lus. Thaum twg cua sov ntau dhau, cov enzymes (txij li lawv yog cov protein nyob ntawm lawv cov duab) dhau los ua qhov tsis sib xws.
Yuav ua li cas thaum amylase boiled?
Boiling ib qho enzyme denatures cov proteins nyob rau hauv, thiab kev ntsuam xyuas iodine - uas hloov cov hmoov txhuv nplej siab nrog rau cov hmoov txhuv nplej siab txuas ntxiv - qhia seb cov hmoov txhuv nplej siab puas tau tawg mus rau saccharides.

Yuav muaj dab tsi tshwm sim thaum cov tshuaj neurotransmitter raug tso tawm los ntawm presynaptic cell?
Hauv kev teb rau qhov muaj peev xwm ua tau zoo lossis muaj peev xwm ua tau hluav taws xob, lub paj hlwb tau tso tawm ntawm lub dav hlau presynaptic. Kev tso tawm cov neurotransmitter tuaj yeem txav mus los hla cov synapse kom pom los ntawm thiab khi nrog cov neeg txais khoom hauv lub paj hlwb postsynaptic
Yuav ua li cas tshwm sim thaum rods thiab cones raug rau lub teeb quizlet?
Thaum raug qhov tsaus ntuj, cov rods thiab cones yog depolarized thiab yog li tso tawm ntau neurotransmitter dua lub teeb. Tsis rhiab rau lub teeb, lub luag haujlwm rau nruab hnub lossis duab lossis pom kev xim. tus pas nrig ib ntawm ob hom receptor rau photic zog; muaj cov photopigment rhodopsin, rhiab rau lub teeb
Yuav ua li cas tshwm sim thaum ib tug fallopian raj raug tshem tawm?
Kev tshem tawm ntawm ib lub raj yas yuav tsis ua rau koj ntxiv lawm. Koj tseem yuav xav tau kev tiv thaiv kab mob. Kev tshem tawm ob txoj hlab ntsha hauv plab txhais tau tias koj xeeb tsis tau menyuam thiab yuav tsis xav tau kev tiv thaiv. Txawm li cas los xij, yog tias koj tseem muaj koj lub tsev menyuam, nws tuaj yeem nqa tus menyuam nrog kev pabcuam hauv vitro fertilization (IVF)
Yuav ua li cas tshwm sim thaum lub cev raug tshav kub?
Thaum tshav kub kub stroke - mob mob tshwm sim los ntawm overexposure rau tshav kub. Cov tsos mob qhuav, tawv nqaij kub, lub cev kub (feem ntau tshaj 105F) thiab puas hlwb. Thaum tshav kub kub syncope - ib ntus tsis nco qab tshwm sim los ntawm cov ntshav tsis txaus mus rau lub hlwb
Yuav ua li cas tshwm sim thaum acetylcholine receptors raug thaiv?
Cobras thiab Curare Lub acetylcholine receptor yog qhov txuas tseem ceeb ntawm lub hlwb thiab cov leeg, yog li nws yog qhov chaw nkag siab yooj yim rau kev tawm tsam. Ntau yam kab mob ua rau cov tshuaj lom uas thaiv cov acetylcholine receptor, ua rau tuag tes tuag taw
