Receptors yog feem ntau transmembrane cov proteins , uas khi rau signaling molecules sab nraum lub xovtooj ntawm tes thiab tom qab ntawd xa cov teeb liab los ntawm ib ntu ntawm cov hloov pauv molecular mus rau hauv cov kev taw qhia sab hauv. Ib qho acetylcholine tus neeg txais kev pab (ntsuab) tsim ib qho gated ion channel hauv plasma membrane.
Kuj nug, dab tsi yog qhov ua haujlwm ntawm receptor protein?
Receptors yog cov proteins lossis glycoprotein uas khi cov cim qhia cov khoom siv hu ua thawj cov tub txib, lossis ligands. Lawv tuaj yeem pib qhov kev taw qhia cascade, lossis tshuaj teb, uas ua rau cell kev loj hlob, kev faib, thiab kev tuag los yog qhib cov hlab ntsha.
Ib sab saum toj, yuav ua li cas yog tias receptor protein hloov pauv? Cov qauv kev hloov pauv provoked los ntawm kev hloov pauv los yog variations nyob rau hauv cov noob coding rau GPCRs tej zaum yuav ua rau misfolding, hloov plasma membrane qhia ntawm lub receptor protein thiab nquag mus rau kab mob.
Tom qab ntawd, dab tsi yog qhov piv txwv ntawm receptor protein?
Piv txwv ntawm cov protein receptor / cov receptors suav: a. Guanine nucleotide-binding protein ntau - ua ke cov receptors (GPCRs) (metabotropic). b. serine threonine kinases (SerThr Kinase): TGF-β; MAPK cascade; phosphoinositol kinase-related kinase (PIKK) tsev neeg - mTOR (FRAP1), ATM, ATR, DNA-PK.
Cov protein thauj khoom ua li cas?
Thauj cov proteins ua qhov rooj rau lub cell , pab qee cov molecules hla rov qab mus rau hauv cov plasma membrane, uas nyob ib puag ncig txhua tus neeg nyob cell . Nyob rau hauv passive thauj molecules txav los ntawm ib cheeb tsam ntawm siab concentration mus rau qhov chaw uas tsis muaj concentration.

Teb thiab piav qhia: Tus nqi ntawm tus lej complex, 2i, yog 2
AG protein receptor yog dab tsi?
G protein-coupled receptor (GPCR), tseem hu ua xya-transmembrane receptor lossis heptahelical receptor, protein nyob rau hauv cov cell membrane uas khi cov tshuaj extracellular thiab xa cov teeb liab los ntawm cov tshuaj mus rau ib qho intracellular molecule hu ua G protein (guanine nucleotide-binding protein)
Dab tsi yog qhov txawv ntawm ib puag ncig lapse tus nqi thiab adiabatic lapse tus nqi?
A. Ib puag ncig lapse tus nqi yog hais txog qhov kub thiab txias nrog nce qhov siab hauv troposphere; uas yog qhov kub ntawm ib puag ncig ntawm qhov chaw sib txawv. Nws implies tsis muaj huab cua txav. Adiabatic txias tsuas yog cuam tshuam nrog huab cua ascending, uas txias los ntawm kev nthuav dav
Qhov tshwm sim yog dab tsi uas lawv tus menyuam yuav muaj tus kabmob?
Feem ntau, yog tias ib tus niam txiv tsis yog tus neeg nqa khoom, qhov tshwm sim uas tus menyuam yuav muaj tus kabmob yog: ½ lub sij hawm (qhov tshwm sim rau lwm tus niam txiv yog tus nqa khoom). Qhov ntawd yog, peb muab qhov tshwm sim ntawm kev kis tus kab mob allele, & frac12, lub sij hawm qhov tshwm sim uas niam txiv ua, qhov tseeb, nqa tus kab mob allele
Tus qauv qauv yog dab tsi Qhov txawv ntawm tus qauv qauv thiab tus qauv molecular yog dab tsi?
Cov mis mos molecular siv cov cim tshuaj thiab cov ntawv sau npe los qhia cov naj npawb ntawm cov atoms sib txawv hauv cov molecule lossis compound. Ib qho empirical formula muab qhov yooj yim tshaj plaws, tag nrho tus lej piv ntawm atoms hauv ib qho chaw. Cov qauv qauv qhia txog kev sib koom ua ke ntawm cov atoms hauv cov molecule
