Thaum khi rau ib lub ligand, hom kev hloov pauv no ua kom cov ions txav mus rau lawv cov concentration gradient hla cov membrane. Siv cov tshuaj tshwj xeeb, tus kws kho mob ntawm tes tau thaiv ib hom channel txuas receptor nyob rau hauv ib lab nas lub siab cov ntaub so ntswg. Dab tsi yog qhov yuav siv tau ntawm cov tshuaj nws siv?
Yuav ua li cas thaum lub ligand khi rau tus neeg txais?
Lub ligand hla lub plasma membrane thiab khi rau tus receptor hauv cytoplasm. Tus receptor ces txav mus rau lub nucleus, qhov twg nws khi DNA los tswj kev hloov pauv. … Ntau yam kev taw qhia, uas muaj ob qho tib si intracellular thiab cell nto receptors, ua rau kev hloov pauv ntawm cov noob.
Dab tsi yog hom receptors uas tuaj yeem khi ligands?
Peb yam dav dav ntawm cov cell-nto receptors suav nrog: ion -channel, G- protein, thiab enzyme-linked protein receptors. Ion channel -linked receptors khi ib lub ligand thiab qhib ib lub channel los ntawm daim nyias nyias uas tso cai rau cov ions tshwj xeeb kom dhau mus.
Yuav ua li cas thaum lub ligand khi rau qhov receptor quizlet?
Kev khi ntawm lub ligand rau ib qho receptor ua rau kev hloov pauv hauv cov receptor uas pib ua ntu zus ntawm cov tshuaj tiv thaiv ua rau cov lus teb tshwj xeeb hauv lub xov tooj.
Lub ligand khi receptor ua rau dab tsi?
Signal transduction therapy
Ligand khi rauKev loj hlob ntawm angiogenic receptors ua rau kom ua rau downstream intracellular signaling pathways thiab tom qab hloov pauv ntawm cov noob qhia thiab cov cwj pwm ntawm tes.

Semiconservative replication piav qhia txog cov txheej txheem ntawm DNA replication nyob rau hauv tag nrho cov paub hlwb. DNA replication tshwm sim ntawm ntau lub hauv paus pib ntawm kev rov ua dua raws DNA qauv strand. Raws li DNA ob chav helix yog unwound by helicase, replication tshwm sim nyias ntawm txhua tus qauv strand nyob rau hauv antiparallel cov lus qhia.
Qhov kev hloov pauv twg yog xav tias yuav cuam tshuam los ntawm kev hloov pauv hloov pauv?
Dependent Variable Qhov sib txawv uas nyob ntawm lwm yam uas ntsuas. Cov kev hloov pauv no yuav tsum tau hloov pauv raws li qhov kev sim ua haujlwm ntawm tus kheej hloov pauv lossis hloov pauv. Nws yog cov nyhuv presumed. Qhov kev tshawb fawb hloov pauv twg yog qhov tshwm sim?
