Lub luag haujlwm ntawm cov enzymes hauv metabolism . Ib txhia cov enzymes pab kom zom cov zaub mov loj, xws li cov protein, rog, thiab carbohydrates, mus rau hauv me me molecules. Txhua enzyme muaj peev xwm txhawb nqa tsuas yog ib hom tshuaj tiv thaiv. Cov compounds uas cov enzyme kev ua yog hu ua substrates.
Ib yam li ntawd, koj tuaj yeem nug, dab tsi enzymes koom nrog hauv cov metabolism?
Cov kev pab txhawb nqa lub neej no yog qhov tseem ceeb rau kev loj hlob thiab kev saib xyuas ntawm cellular kev ncaj ncees. Metabolic enzymes encompass ntau hom protein ntau, suav nrog carboxylases, dehydrogenases, lipoxygenases, oxidoreductases, kinases, lyases, transferases, thiab ntau dua.
Kuj Paub, ua li cas enzymes catalyze metabolic tshua? Enzymes yog protein catalysts ceev biochemical cov tshuaj tiv thaiv los ntawm kev yooj yim cov molecular rearrangements uas txhawb kev ua haujlwm ntawm tes. Nco qab tias tshuaj cov tshuaj tiv thaiv hloov substrates rau hauv cov khoom, feem ntau los ntawm kev txuas cov tshuaj lom neeg rau los yog rhuav tshem cov tshuaj lom neeg los ntawm cov substrates.
Yog li ntawd, dab tsi yog kev sib raug zoo ntawm enzymes thiab metabolism?
Enzymes speeds tus nqi ntawm metabolic cov tshuaj tiv thaiv los ntawm kev txo qis lub zog ua kom muaj zog. Thaum ib enzyme khi rau ib lub substrate, nws stresses thiab destabilizes daim ntawv cog lus nyob rau hauv lub substrate. Qhov no txo qhov zuag qhia tag nrho lub zog ntawm theem ntawm substrate hloov pauv xeev. Tus nqi tshuaj tiv thaiv yog tus nqi ntawm cov tshuaj tiv thaiv lub sijhawm.
Vim li cas cov enzymes xav tau cofactors?
Cofactors yog inorganic substrate. Ib txhia cofactors yuav tsum tau tsim cov tshuaj tiv thaiv ntawm cov enzyme thiab cov substrate, thaum lwm tus tsuas yog nce tus nqi ntawm catalysis. Cofactors muaj qee zaum txuas rau enzyme , zoo ib yam li lub caj dab prosthetic. Lwm tus yog loosely khi rau lub enzyme.

Yuav ua li cas cov protein tswj cov kev qhia gene?
Eukaryotic gene qhia yog tswj thaum lub sij hawm transcription thiab RNA ua, uas tshwm sim nyob rau hauv lub nucleus, thiab thaum lub sij hawm lub protein txhais lus, uas tshwm sim nyob rau hauv lub cytoplasm. Cov kev cai ntxiv tuaj yeem tshwm sim los ntawm kev hloov pauv tom qab kev hloov pauv ntawm cov protein
Yuav ua li cas cov tshuaj tiv thaiv kab mob tswj nyob rau hauv lub nuclear reactor?
Nyob rau hauv lub chaw nres tsheb hluav taws xob nuclear nuclear hluav taws xob tau txais kev tswj xyuas cov tshuaj tiv thaiv hauv lub reactor los tsim cov cua sov - nuclear rau cua sov zog. Cov tshuaj tiv thaiv kab mob yog tswj los ntawm Boron tswj rods. Thaum Boron absorbs cov neutrons ces cov tshuaj tiv thaiv kab mob yuav qeeb vim tsis muaj neutrons tsim cov tshuaj tiv thaiv
Dab tsi yog kev tswj zoo thiab kev tswj tsis zoo hauv gel electrophoresis?
Kev tswj qhov zoo thiab qhov tsis zoo yog cov qauv uas tau siv los lees paub qhov siv tau ntawm gel electrophoresis sim. Cov kev tswj tau zoo yog cov qauv uas muaj cov cim paub txog DNA lossis cov protein thiab yuav txav mus rau ib txoj hauv kev tshwj xeeb ntawm cov gel. Kev tswj tsis zoo yog cov qauv uas tsis muaj DNA lossis cov protein
Cov cai tswj kev tswj hwm yog dab tsi?
Kev hloov pauv hauv lub dav hlau sib koom tes feem ntau yog sawv cev los ntawm 'coordinate rules' ntawm daim ntawv (x, y) --> (x', y'). Qhov no txhais tau hais tias ib lub ntsiab lus uas nws cov kev tswj hwm yog (x, y) tau kos npe rau lwm lub ntsiab lus uas nws cov kev tswj hwm yog (x', y')
Yuav ua li cas morphogenesis cuam tshuam los ntawm kev tswj cov noob qhia?
Gene qhia cuam tshuam morphogenesis los ntawm kev tswj cov kab mob dab tsi yuav tig tawm zoo li. Kev sib txawv ntawm tes txawv li cas ntawm morphogenesis? Kev sib txawv ntawm tes yog thaum qia hlwb ua ntau hom hlwb xws li: tawv nqaij, ntshav, pob txha, thiab lwm yam. Morphogenesis yog kev loj hlob ntawm lub cev
