Plaub qhov tshwj xeeb ntawm gluconeogenesis yog pyruvate carboxylase, nyob hauv mitochondrialmatrix, phosphoenolpyruate (PEP) carboxykinase nyob rau hauv mitochondrial matrix thiab cytosol, fructose-1, 6-bisphosphatase nyob rau hauv cytosol thiab qabzib-6-phosphatase nyob rau hauv endoplasmic reticulum (ER).
Dab tsi yog qhov tseem ceeb ntawm gluconeogenic enzymes?
Cov enzymes tshwj xeeb rau gluconeogenesis yog pyruvate carboxylase, PEP carboxykinase, fructose 1, 6-bisphosphatase, thiab qabzib 6-phosphatase.
Dab tsi yog 3 qhov kev cuam tshuam dhau los ntawm gluconeogenesis?
Peb qhov kev cuam tshuam ntawm glycolysis uas tau ua nrog kev hloov pauv tsis zoo ntawm lub zog loj yog hla thaum lub sijhawm gluconeogenesis los ntawm kev siv cov enzymes sib txawv. Peb cov no yog cov pyruvate kinase, phosphofructokinase-1 (PFK-1) thiab hexokinase / glucokinase catalyzed cov tshuaj tiv thaiv.
Dab tsi yog cov enzymes koom nrog hauv cov kauj ruam uas tsis tuaj yeem hloov tau?
Txoj kev gluconeogenesis, uas tau paub tias ib txwm muaj nyob rau hauv daim siab, lub raum, txoj hnyuv, lossis cov leeg, muaj plaub kauj ruam uas tsis tuaj yeem hloov pauv los ntawm cov enzymes: pyruvate carboxylase, phosphoenolpyruvate carboxykinase, fructose 1, 6-bisphosphatase, thiab qabzib 6-phosphatase.
Dab tsi yog 4 cov enzymes tswj hauv gluconeogenesis?
Txawm hais tias gluconeogenesis yog theoretically qhov thim rov qab ntawm glycolysis, muaj peb qhov tseem ceeb irreversible glycolysis kinase cov tshuaj tiv thaiv catalyzed los ntawm glucokinase (GK), phosphofructokinase-1 (PFK-1), thiab pyruvate kinase (PK) (7), uas yog kov yeej los ntawm plaub lub cim gluconeogenic enzymes suav nrog PC, PEPCK, FBPase, thiab G6Pase(…
