Video: Yuav ua li cas thaum lub teeb liab transduction?

Teeb liab transduction yog cov txheej txheem uas muaj tshuaj lom neeg lossis lub cev teeb liab yog kis los ntawm ib tug cell raws li ib tug series ntawm molecular txheej xwm, feem ntau cov protein phosphorylation catalyzed los ntawm cov protein kinases, uas thaum kawg tshwm sim. hauv cellular teb.
Tsis tas li ntawd, 3 theem ntawm cell signaling yog dab tsi?
Peb theem ntawm Cell Signaling
- Ua ntej, txais tos, qhov twg lub teeb liab molecule khi lub receptor.
- Tom qab ntawd, cov teeb liab transduction, uas yog qhov chaw tshuaj lom neeg teeb liab tshwm sim nyob rau hauv ib tug series ntawm enzyme activations.
- Thaum kawg, cov lus teb, uas yog cov lus teb ntawm tes.
Tsis tas li ntawd, ib qho piv txwv ntawm cov teeb liab hloov pauv yog dab tsi? Epinephrine yog siv los ua tus qauv xa mus rau kev tso tawm cov piam thaj los ntawm cov hlwb hauv lub siab. G-Protein, adenylyl cyclase, cAMP, thiab protein kinases yog txhua yam siv los ua piv txwv. piv txwv ntawm cov teeb liab transduction.
Tom qab ntawd, lub teeb liab transduction nres li cas?
Ligand khi rau lub receptor tso cai rau teeb liab transduction dhau ntawm lub cell. Cov saw ntawm cov xwm txheej uas conveys lub teeb liab dhau ntawm lub cell yog npe a teeb liab txoj kev los yog cascade. Ib txoj hauv kev txiav tawm lossis nres ib qho tshwj xeeb teeb liab yog kom degrade los yog tshem tawm cov ligand kom nws ua tau tsis nkag mus rau nws receptor lawm.
Dab tsi yog cov kauj ruam hauv cov teeb liab transduction?
Theem ntawm Kev Hloov Pauv Hloov
- Muaj peb theem nyob rau hauv tus txheej txheem ntawm cell signaling los yog kev sib txuas lus:
- Kev txais tos-cov protein ntawm lub xovtooj ntawm tes pom cov cim tshuaj.
- Kev hloov pauv-kev hloov pauv hauv cov protein txhawb nqa lwm yam kev hloov pauv xws li teeb liab-transduction txoj hauv kev.
- Teb-yuav luag txhua yam kev ua ntawm tes.

Yuav ua li cas tshwm sim thaum magma txias thaum lub sij hawm lub pob zeb quizlet?
Raws li cov magma cools, loj thiab loj muaju tsim raws li lub pob zeb hardens. Yog tias magma tawm hauv lub ntiaj teb, lub pob zeb molten tam sim no hu ua lava. Thaum cov lava no txias rau ntawm lub ntiaj teb saum npoo, nws tsim cov pob zeb extrusive igneous. Lava txias sai heev, yog li cov pob zeb extrusive igneous tsis muaj crystals zoo
Dab tsi yog cov kauj ruam ntawm lub teeb liab transduction txoj kev?
Peb theem ntawm Cell Signaling Cell signaling tuaj yeem muab faib ua 3 theem. Kev txais tos: Ib lub xovtooj ntawm tes pom ib qho kev taw qhia molecule los ntawm sab nraud ntawm tes. Transduction: Thaum lub teeb liab molecule khi cov receptor nws hloov cov receptor protein nyob rau hauv qee txoj kev. Teb: Thaum kawg, lub teeb liab ua rau cov lus teb tshwj xeeb ntawm tes
Vim li cas peb thiaj cia siab tias cov kab mob Gram tsis zoo yuav stain liab liab thaum lub sij hawm Gram staining txheej txheem?
Thaum cov kab mob gram zoo stain violet vim muaj cov txheej txheem peptidoglycan tuab nyob rau hauv cov phab ntsa ntawm lawv cov cell, cov kab mob gram tsis zoo stain liab, vim yog cov txheej peptidoglycan thinner hauv lawv cov phab ntsa ntawm tes (peptidoglycan txheej tuab dua tso cai rau cov kab mob gram zoo stains violet. tuav lub stain, tab sis ib txheej nyias
Dab tsi yog qhov txawv ntawm wavelength ntawm lub teeb liab thiab lub teeb violet?
Violet lub teeb yog hluav taws xob hluav taws xob hluav taws xob nrog wavelengths ntawm 410 nanometers thiab lub teeb liab muaj awavelength ntawm 680 nanometers. Qhov ntau ntawm wavelengths (400 - 700 nm) ntawm lub teeb pom kev yog nyob nruab nrab ntawm lub electromagnetic spectrum (Fig.1)
Vim li cas cov kab mob Gram tsis zoo tshwm liab liab thaum cov kab mob Gram zoo pom ntshav liab?
Gram zoo hlwb stain ntshav vim lawv cov peptotidoglycan txheej yog tuab txaus, txhais tau tias tag nrho cov kab mob Gram zoo yuav khaws lawv cov stain. Gram tsis zoo hlwb stain liab vim lawv muaj ib tug nyias peptidoglycan phab ntsa, thiab lawv yuav tsis khaws ib yam ntawm cov ntshav stain los ntawm crystal violet
