Qhov Tseem Ceeb Qhov txawv - Substrate vs Khoom
Qhov sib txawv tseem ceeb ntawm substrate thiab cov khoom lag luam yog cov substrate yog cov khoom siv tshuaj lom neeg cov tshuaj tiv thaiv thaum cov khoom yog cov khoom sib xyaw tau txais tom qab ua tiav cov tshuaj tiv thaiv.
Cov ntsiab lus substrate thiab cov khoom siv yog siv los ua cov tshuaj tiv thaiv ib puag ncig thiab hauv cov tshuaj tiv thaiv uas ib qho enzyme ua raws li catalyst. Lub substrate yog lub compound uas lub enzyme ua rau. Cov khoom yog cov khoom sib xyaw uas tau txais thaum cov tshuaj tiv thaiv tiav.
Dab tsi yog Substrate?
Substrate yog cov khoom pib hauv cov tshuaj tiv thaiv. Substrate yog cov khoom sib xyaw uas tau hloov kho lossis hloov kho dua tshiab thaum muaj tshuaj lom neeg. Rau biochemical cov tshuaj tiv thaiv, lub substrate yog cov compound uas ib tug enzyme ua. Lub concentration ntawm substrate hloov nrog lub sij hawm ntawm kev loj hlob ntawm cov tshuaj tiv thaiv; lub substrate concentration txo. Muaj peev xwm muaj ib lossis ntau lub substrates koom nrog hauv cov tshuaj tiv thaiv.
Daim duab 01: Substrate thiab Khoom hauv Biochemical Reaction
Thaum xav txog cov tshuaj biochemical, cov substrate khi rau cov enzyme. Lub substrate tau txuas mus rau qhov chaw ntawm cov enzyme hu ua active sites. Tom qab ntawd, cov ntaub ntawv substrate-enzyme complex. Cov tshuaj tiv thaiv tshwm sim ntawm cov enzyme. Cov khoom ntawm cov tshuaj tiv thaiv raug tso tawm los ntawm qhov chaw nquag tom qab.
khoom yog dab tsi?
Cov khoom yog cov khoom sib xyaw uas tau txais thaum kawg ntawm cov tshuaj tiv thaiv tshuaj. Cov khoom yog qhov tshwm sim los ntawm cov tshuaj tiv thaiv. Muaj peev xwm muaj ib lossis ntau yam khoom tau los ntawm cov tshuaj tiv thaiv. Cov khoom pib ntawm cov tshuaj tiv thaiv yog hu ua reactants lossis substrates. Kev kho dua tshiab, kev tsim cov ntawv cog lus lossis kev sib koom ua ke tuaj yeem tshwm sim thaum muaj tshuaj lom neeg los muab cov khoom lag luam.
Daim duab 02: Lub zog daim duab rau qhov kev tshwm sim uas muab C raws li cov khoom
Thaum sau ib qho kev sib npaug rau cov tshuaj tiv thaiv, ib tug xub yog siv los qhia cov kev taw qhia ntawm cov tshuaj tiv thaiv. Nyob ntawd, cov khoom lag luam tau pom ntawm sab xis (uas yog lub taub hau taw qhia rau) thaum cov reactants nyob rau sab laug. Piv txwv li: cov tshuaj tiv thaiv ntawm A thiab B muab C thiab D ua cov khoom. Ces nws yog sau raws li nram no.
A + B → C + D
Cov khoom muab los ntawm cov tshuaj tiv thaiv tshwj xeeb tuaj yeem yog cov khoom loj lossis cov khoom me. Cov khoom lag luam loj yog cov khoom lag luam uas tau muab rau ntawm qhov feem pua siab dua li lwm yam khoom. Cov khoom me me kuj tseem hu ua cov khoom lag luam. Qee zaum, cov tshuaj muaj pes tsawg leeg ntawm cov reactant thiab cov khoom zoo sib xws, tsuas yog theem ntawm cov teeb meem txawv.

Summary – Substrate vs Product
Substrates thiab cov khoom muaj nyob rau hauv cov tshuaj tiv thaiv sib tov. Substrates yog cov khoom pib ntawm cov tshuaj tiv thaiv thaum cov khoom tuaj yeem tau txais thaum kawg ntawm cov tshuaj tiv thaiv. Qhov txawv ntawm substrate thiab cov khoom yog tias lub substrate yog cov khoom pib ntawm cov tshuaj tiv thaiv thaum cov khoom yog cov compound tau tom qab ua tiav cov tshuaj tiv thaiv.
