Hexokinase IV muaj nyob hauv lub siab, pancreas, hypothalamus, txoj hnyuv me, thiab tej zaum qee lwm cov hlwb neuroendocrine, thiab ua lub luag haujlwm tseem ceeb hauv kev tswj cov carbohydrate metabolism.
hexokinase nyob qhov twg hauv lub cev?
Hexokinase IV qhia txog kev sib koom tes zoo nrog cov piam thaj thiab tsis cuam tshuam los ntawm cov piam thaj-6-phosphate, tsis zoo li hexokinases I, II thiab III. Nws muaj nyob hauv lub siab, txiav txiav, hypothalamus thiab txoj hnyuv. Nws kuj tseem tuaj yeem muaj nyob hauv lwm cov hlwb neuroendocrine.
YPuas hexokinase pom nyob rau hauv tag nrho cov ntaub so ntswg?
-Hexokinase I/A tau pom nyob rau hauv tag nrho cov ntaub so ntswg mammalian, thiab suav hais tias yog "lub tsev tu enzyme," tsis cuam tshuam los ntawm feem ntau lub cev, hormonal, thiab metabolic hloov.
YPuas muaj glucokinase nyob rau hauv tag nrho cov ntaub so ntswg?
Glucokinase tau tshawb pom hauv cov hlwb tshwj xeeb hauv plaub hom tsiaj cov ntaub so ntswg: daim siab, pancreas, hnyuv me, thiab hlwb. Txhua lub luag haujlwm tseem ceeb hauv kev teb rau qhov nce lossis poob qib ntawm cov ntshav qabzib. Cov hlwb tseem ceeb ntawm daim siab yog cov hepatocytes, thiab GK pom tshwj xeeb hauv cov hlwb no.
YPuas yog hexokinase hauv cov leeg nqaij?
Hexokinase isoforms nyob rau hauv tib neeg skeletal nqaij . Hexokinase isozymes I thiab II tau qhia hauv cov leeg pob txha (3). Cov leeg nqaij pob txha muaj feem ntau hom II enzyme (1, 5), thaum tib neeg cov leeg muaj kwv yees li sib npaugntau hom II thiab hom I isoforms (19, 21, 40).

Dab tsi yog peb cov ntaub qhwv cov ntaub so ntswg hauv cov leeg?
Cov ntaub so ntswg interstitial ntawm cov leeg yog subdivided rau hauv epimysium epimysium Lub epimysium yog cov ntaub so ntswg ntom ntom uas nyob ib puag ncig tag nrho cov leeg nqaij. Lub epimysium feem ntau muaj ntau pob (fascicles) ntawm cov leeg nqaij.
Dab tsi yog cov kab mob photosynthetic pom nyob rau hauv cov ntaub so ntswg ntawm coral?
Feem ntau cov pob zeb tsim cov pob zeb muaj cov photosynthetic algae, hu ua zooxanthellae, uas nyob hauv lawv cov ntaub so ntswg. Corals thiab algae muaj kev sib raug zoo. Lub coral muab cov algae nrog kev tiv thaiv ib puag ncig thiab cov tebchaw uas lawv xav tau rau photosynthesis.
Nyob rau hauv convection tam sim no cov ntaub ntawv kub txav?
Convection currents yog qhov tshwm sim ntawm sib txawv cua sov. Lub teeb (tsawg ntom), cov khoom sov tuaj thaum hnyav (ntau dua) cov khoom txias dab dej. Nws yog qhov kev txav no uas tsim cov qauv kev ncig hu ua convection tam sim no hauv huab cua, hauv dej, thiab hauv lub mantle ntawm lub ntiaj teb.
Nyob rau hauv cov ntaub so ntswg extraembryonic puas tshwm sim hematopoiesis?
In the mesoderm txheej yog cov yolk sac blood islands blood islands Blood islands yog structures nyob ib ncig ntawm lub embryo tsim uas ua rau ntau qhov sib txawv ntawm cov hlab ntsha.. Ntshav cov Islands tuaj tshwm rau sab nraud rau kev loj hlob embryo nyob rau hauv lub plab vesicle, allantois, txuas stalk thiab chorion.
Puas cov ntaub so ntswg epithelial puas muaj cov ntaub so ntswg hauv qab daus?
Ntseeg ntawm Epithelia Epithelial hlwb txuas rau ib hom tshwj xeeb ntawm extracellular matrix hu ua basal lamina basal lamina Lub basal lamina yog txheej ntawm extracellular matrix secreted los ntawm cov epithelial hlwb, ntawm uas lub epithelium zaum.
