Glycogenesis tshwm sim thaum cov ntshav qabzib siab txaus kom tso cov piam thaj ntau dhau los khaws cia hauv daim siab thiab cov leeg nqaij. Glycogenesis yog txhawb nqa los ntawm cov tshuaj insulin.
Glycogenesis ua haujlwm li cas?
Glycogenesis yog txheej txheem ntawm glycogen synthesis, nyob rau hauv uas cov piam thaj molecules ntxiv rau chains ntawm glycogen cia. Cov txheej txheem no tau qhib thaum lub sijhawm so tom qab lub voj voog Cori, hauv daim siab, thiab tseem qhib los ntawm insulin hauv cov lus teb rau qib qabzib siab.
Koj ua li cas thiaj txhawb nqa gluconeogenesis?
Gluconeogenesis yog txhawb los ntawm cov tshuaj hormones ntshav qab zib (glucagon, kev loj hlob hormone, epinephrine, thiab cortisol). Gluconeogenic substrates suav nrog glycerol, lactate, propionate, thiab qee cov amino acids.
Dab tsi txhawb nqa gluconeogenesis thiab glycogenolysis?
Raws li lub cev endocrine, pancreas zais ntau cov tshuaj hormones uas suav nrog insulin (los ntawm β hlwb hauv cov islets ntawm Langerhans), glucagon (los ntawm α hlwb), thiab somatostatin (los ntawm δ cells). … Hauv qhov sib piv, glucagon secreted thaum yoo mov nkoos gluconeogenesis thiab glycogenolysis.
Dab tsi ua rau Glycogenolysis?
Glycogenolysis yog txhawb nqa los ntawm glucagon, uas yog kho los ntawm kev nce hauv cellular ntawm cAMP thiab Ca + 2, uas yog kho los ntawm adenylate cyclase lossis phospholipase C txoj hauv kev. Glucagon activates adenylate cyclase ntawm GR2 receptors.
