Zymogen granules (ZGs) yog cov khoom tshwj xeeb khaws cia nyob rau hauv lub exocrine pancreas uas tso cai rau kev txheeb, ntim thiab tswj apical secretion ntawm digestive enzymes. ZG cov neeg koom nrog ua lub luag haujlwm tseem ceeb hauv kev raug mob pancreatic thiab kab mob. Cov txheej txheem molecular hauv qab cov txheej txheem no tseem txhais tau tsis zoo.
Cov hlwb twg muaj zymogen granules?
Cov granules no muaj nyob hauv secretory cells hu ua zymogen cells. Zymogen yog muab los ntawm Greek zyme uas txhais tau tias ferment thiab noob caj noob ces txhais tau tias tsim.
zymogen cells nyob qhov twg?
ua haujlwm hauv plab zom mov
Nyob hauv lub caj pasyog cov zymogenic (tus thawj) hlwb, uas xav tias tsim cov enzymes pepsin thiab rennin.
Zimogens muab piv txwv li cas?
Ib qho piv txwv ntawm zymogen yog pepsinogen. Pepsinogen yog qhov ua ntej ntawm pepsin. Pepsinogen tsis ua haujlwm kom txog thaum nws tso tawm los ntawm cov hlwb tseem ceeb hauv HCl. … Pepsinogen yuav raug hloov mus rau hauv pepsin tag nrho thaum lub tsev tiv thaiv peptide raug tshem tawm.
piv txwv ntawm Proenzyme yog dab tsi?
Proenzyme yog qhov ua ntej ntawm ib qho enzyme, xav tau qee qhov kev hloov pauv (feem ntau yog qhov hydrolysis ntawm ib qho inhibiting fragment uas npog ib pawg active) kom nws nquag; Piv txwv li, pepsinogen, trypsinogen, profibrolysin.
