Cov tso tawm glucagon yog txhawb nqa los ntawm cov ntshav qab zib qis, cov zaub mov muaj protein ntau thiab adrenaline (lwm yam tshuaj tseem ceeb rau kev sib ntaus cov piam thaj qis). Cov kev tso tawm ntawm glucagon yog tiv thaiv los ntawm nce ntshav qabzib thiab carbohydrate hauv cov zaub mov, kuaj pom los ntawm cov hlwb hauv pancreas.

Kuj nug, dab tsi txhawb kev tso tawm ntawm insulin?

Cov tshuaj insulin feem ntau yog secreted los ntawm beta hlwb (ib hom islet cell) ntawm pancreas. Qhov kev txhawb zog rau insulin secretion yog HIGH ntshav qabzib yooj yim li ntawd! Txawm hais tias yeej ib txwm muaj qib qis cov tshuaj insulin secreted los ntawm pancreas, tus nqi secreted rau hauv cov ntshav nce raws li cov ntshav qabzib nce.

Dab tsi tshwm sim nce ob qho tib si glucagon thiab insulin tso tawm? Ob leeg glucagon thiab insulin tso tawm yog txhawb nqa los ntawm kev noj cov amino acids, xav tias yuav txo qis hypoglycemia yog tias noj cov protein ntshiab. Hauv cov tib neeg ib txwm muaj, glucagon tso tawm yog txhawb los ntawm hypoglycemia, cov txheej txheem tiv thaiv kom tswj ntshav qabzib concentration homeostasis.

Kuj Paub, glucagon ua haujlwm li cas?

Glucagon stimulates kev tawg ntawm glycogen khaws cia hauv daim siab. Tom qab ntawd, thaum cov ntshav qabzib pib poob, glucagon yog zais thiab ua haujlwm ntawm hepatocytes rau qhib cov enzymes uas depolymerize glycogen thiab tso cov piam thaj. Glucagon ua haujlwm kab mob siab gluconeogenesis.

Vim li cas glucagon txhawb nqa los ntawm cov amino acids?

Ib qho kev nce hauv amino acid Kev sib txuas nrog pancreatic A-hlwb yog ua raws li a kev txhawb nqa ntawm glucagon tso tawm. Thaum B-cells ua haujlwm tsis zoo thiab teb ua ke rau qhov amino acid , cov piam thaj hloov pauv tau nce ntxiv thiab cov ntshav glycose concentration tseem nyob li qub.
