Acid hauv peb plab plays ib qho tseem ceeb luag hauj lwm hauv lub cev tiv thaiv kab mob los ntawm kev tua cov kab mob phem thiab cab uas tau noj nrog zaub mov. Lub plab acid ua kom cov enzyme pepsin xav tau rau kev zom cov protein. Lub plab acid Cov cim qhia rau pancreas tsim cov kua txiv hmab txiv ntoo thiab cov enzymes kom zom cov zaub mov ntxiv.
Tsis tas li ntawd, lub luag haujlwm ntawm cov kua qaub hauv peb lub cev yog dab tsi?
Cov kua qaub ua si tseem ceeb lub luag haujlwm hauv tib neeg lub cev . Cov tshuaj hydrochloric kua qaub tam sim no hauv plab pab plab zom mov los ntawm kev zom cov zaub mov loj thiab nyuaj. Amino cov kua qaub yog xav tau los ua ke cov protein uas xav tau rau kev loj hlob thiab kho ntawm lub cev cov ntaub so ntswg.
Ib sab saum toj, dab tsi yog ob txoj haujlwm ntawm lub plab acid? Koj HCl muaj plaub txoj haujlwm loj: 1) proteolysis, cov txheej txheem uas cov proteins tau tawg mus rau qhov uas lawv tuaj yeem zom tau; 2) ua kom cov pepsin, lwm enzyme tsim nyog rau cov protein kev zom zaub mov ; 3) tshuaj lom lub cim qhia tias zaub mov tuaj yeem hla ntawm lub plab mus rau txoj hnyuv me nrog rau ceeb toom rau tus txiav txiav
Kuj tseem paub, lub luag haujlwm ntawm HCl hauv koj lub plab yog dab tsi?
Cov plab hnyuv ntawm plab zais kua txiv plab. Hydrochloric kua qaub tswj a muaj zog acidic pH txog li 1.5 txog 2.5 hauv plab . HCl tua cov kab mob thiab lwm yam kab mob uas yuav muaj nrog rau cov zaub mov. HCl converts pepsinogen thiab prorennin rau pepsin thiab rennin feem.
Cov zaub mov twg muaj kua qaub?
Khoom noj khoom haus thiab dej qab ntsev
- nplej.
- qab zib.
- qee yam khoom siv mis nyuj.
- ntses.
- cov zaub mov tiav
- cov nqaij tshiab thiab cov nqaij ua tiav, xws li nqaij nyug pob kws thiab qaib cov txwv.
- dej qab zib thiab lwm yam dej qab zib.
- cov khoom noj muaj protein ntau thiab cov tshuaj ntxiv.

Lub luag haujlwm thiab lub luag haujlwm ntawm cov koom nrog hauv kev faib tshuaj yog dab tsi?
Lub luag haujlwm txoj haujlwm: Txheeb xyuas thiab faib tshuaj raws li daim ntawv yuav tshuaj. Xyuas kom tus neeg mob kos npe rau daim ntawv yuav tshuaj thiab sau nqi raws li xav tau. Txhawm rau khaws cov khoom faib tawm thiab tswj cov khoom lag luam kom zoo ntawm ob qho tshuaj thiab ntim khoom
Vim li cas cov kua qaub thiab enzymes hauv plab tsis nquag zom plab hauv plab?
STOMACH tsis zom nws tus kheej vim tias nws tau hlua nrog cov epithial cells, uas tsim cov hnoos qeev. Qhov no ua ib qho teeb meem ntawm sab hauv ntawm lub plab thiab cov ntsiab lus. Enzymes, uas ua ib feem ntawm cov kua txiv zom zaub mov kuj tseem zais los ntawm lub plab phab ntsa, los ntawm cov qog uas tsis muaj qhov thaiv qhov ncauj
Lub tshuab ua pa ua lub luag haujlwm dab tsi hauv cov kua qaub hauv paus?
Cov kab mob ua pa ua rau muaj kev sib npaug ntawm cov kua qaub thiab cov hauv paus hauv lub cev los ntawm kev tswj cov ntshav qib carbonic acid (Daim duab 2). CO2 nyob rau hauv cov ntshav tau yooj yim reacts nrog dej los tsim carbonic acid, thiab cov theem ntawm CO2 thiab carbonic acid nyob rau hauv cov ntshav yog nyob rau hauv equilibrium
Dab tsi tiv thaiv lub plab hauv plab los ntawm cov kua qaub?
Hauv plab ntau yam txheej txheem tiv thaiv mucosal tiv thaiv lub plab tawm tsam hydrochloric acid thiab cov tshuaj lom. Kev tiv thaiv ua ntej-epithelial yog ua los ntawm cov mucus-bicarbonate teeb meem. Mucus thiab bicarbonate, secreted los ntawm mucus hlwb, tsim pH gradient tswj lub epithelial cell nto nyob ze nruab nrab pH
Dab tsi yog qhov kev txiav txim ntawm cov kua qaub rau cov enzyme hauv qaub ncaug?
Carbohydrates tau tawg thoob plaws hauv lub plab. Salivary amylase yog ib qho enzyme hauv lub qhov ncauj uas pib zom cov carbohydrates hauv daim ntawv ntawm cov hmoov txhuv nplej los ntawm kev cuam tshuam cov hydrolysis ntawm polysaccharides rau hauv disaccharides. Txawm li cas los xij, qhov chaw tseem ceeb rau kev zom zaub mov carbohydrate yog cov hnyuv me
