Enzymes nyiam pepsin yog tsim nyob rau hauv daim ntawv ntawm pepsinogen, tsis ua haujlwm zymogen. Pepsinogen tau qhib thaum cov thawj coj tso nws mus rau hauv cov kua qaub, uas yog hydrochloric acid ib nrab ua kom nws. Fungi kuj tseem zais plab cov enzymes mus rau hauv ib puag ncig li zymogens.
Ib qho ntxiv, vim li cas Pepsinogen tso tawm hauv daim ntawv tsis ua haujlwm?
Los ntawm secreting pepsin nyob rau hauv nws daim ntawv tsis ua haujlwm , lub plab tiv thaiv kev zom zaub mov ntawm cov protein tiv thaiv hauv ob sab phlu ntawm txoj hnyuv. Cov hlwb tshwj xeeb hauv lub plab zom mov, hu ua thawj lub hlwb, tso tawm pepsin thaum txhawb los ntawm gastrin, lwm yam kab mob hauv plab, thiab acetylcholine, neurotransmitter.
Ib sab saum toj no, Pepsinogen yog ib qho enzyme? Pepsinogen yog ib qho muaj zog thiab muaj protein ntau digestive enzyme secreted los ntawm gastric thawj hlwb raws li ib tug proenzyme thiab ces hloov los ntawm gastric acid nyob rau hauv lub plab lumen mus rau lub active enzyme pepsin. Lub luag haujlwm ntawm pepsin thiab nws qhov ua ntej hauv kev zom zaub mov protein tau piav qhia thawj zaug hauv xyoo pua puv 19.
Ib yam nkaus, tib neeg nug, dab tsi yog qhov tsis muaj zog enzyme?
Ib qho zymogen (tseem hu ua proenzyme) yog ib pawg ntawm cov proteins uas tuaj yeem piav qhia ua ib qho inactive enzyme . Vim nws yog ib qho tsis ua haujlwm precursor, nws tsis tuav ib qho kev ua catalytic. Tawm ntawm qhov chaw nquag tso cai rau enzyme kom dhau los ua haujlwm thiab ua haujlwm rau catalyze cov tshuaj tiv thaiv.
Pepsinogen qhib li cas?
Hauv plab, thawj cov cell tso tawm pepsinogen . Qhov no zymogen yog qhib los ntawm hydrochloric acid (HCl), uas tau tso tawm los ntawm cov hlwb parietal hauv plab plab. Pepsin tshem tawm 44 amino acids los ntawm pepsinogen los tsim ntau pepsin.

Dab tsi yog txoj haujlwm zoo tshaj plaws rau koj lub tsheb kom tsis txhob muaj qhov muag tsis pom?
Zam qhov qhov muag tsis pom kev. Kauj ruam 1: Pib los ntawm kev teeb tsa koj daim iav rearview raws li koj ib txwm xav. Tom qab ntawd, tig koj lub taub hau mus rau sab laug kom nws kov lub qhov rais tsav tsheb. Los ntawm txoj haujlwm ntawd, teeb tsa koj lub tsom iav sab laug kom koj tuaj yeem pom lub ces kaum tom qab ntawm koj lub tsheb
Puas yog ntau tus cwj pwm tsis zoo yog kev puas siab puas ntsws?

Tus kws puas siab puas ntsws puas tau hais txog lub luag haujlwm ntawm kev tsis nco qab hauv kev coj cwj pwm?
Freud (1915) hais txog qhov tseem ceeb ntawm lub siab tsis nco qab, thiab thawj qhov kev xav ntawm Freudian txoj kev xav yog tias lub siab tsis nco qab tswj tus cwj pwm mus rau qib siab dua li tib neeg xav. Tseeb tiag, lub hom phiaj ntawm kev xav txog kev xav yog nthuav qhia kev siv cov tswv yim tiv thaiv no thiab yog li ua rau cov neeg tsis nco qab
Lub luag haujlwm ntawm tus kws saib xyuas mob plawv tsis ua haujlwm yog dab tsi hauv kev saib xyuas cov neeg mob plawv tsis ua haujlwm?
Raws li ib feem ntawm pab pawg, tus kws kho mob lub plawv tsis ua haujlwm tau zoo muab rau muab kev pabcuam rau cov neeg mob thoob plaws txoj kev mob plawv tsis ua haujlwm thiab qhov no yuav tsum muaj kev koom tes ze nrog kws saib xyuas mob hauv thaj chaw tshwj xeeb tshwj xeeb xws li chav kho mob xwm txheej ceev thiab kev kho mob dav/ saib xyuas-ntawm-tus-neeg laus
