Qhov sib txawv tseem ceeb ntawm ribozymes thiab protein enzymes yog tias ribozymes yog RNA molecules uas muaj peev xwm ua kom muaj qee yam kev cuam tshuam biochemical thaum cov protein enzymes yog cov protein molecules uas muaj peev xwm catalyzing feem ntau ntawm cov tshuaj biochemical tshwm sim hauv lub neej. kab mob.
Enzymes yog cov tshuaj lom neeg lom neeg, thiab lawv ceev cov tshuaj biochemical. Feem ntau, tag nrho cov enzymes yog cov proteins uas tsim los ntawm cov amino acids. Yog li ntawd, lawv tseem hu ua protein enzymes. Txawm li cas los xij, muaj cov RNA molecules tshwj xeeb uas tuaj yeem ua cov catalysts ntawm cov tshuaj biochemical tshwj xeeb. Lawv yog cov ribozymes los yog ribonucleic acid enzymes. Yog li ntawd, ob qho tib si ribozymes thiab protein enzymes ua haujlwm tib yam uas yog qhov ua rau muaj kev cuam tshuam biochemical.
Y Ribozymes yog dab tsi?
Ribozymes yog ribonucleic acid molecules uas muaj peev xwm ua kom muaj kev cuam tshuam tshwj xeeb biochemical. Txij li thaum lawv yog RNA molecules, lawv xa mus rau ribonucleic acid enzymes thiab. Cov ribozymes no muaj nyob hauv cov ribosomes. Cov tshuaj tiv thaiv tseem ceeb uas ribozymes catalyze yog cleavage thiab ligation ntawm RNA thiab DNA thiab peptide daim ntawv cog lus tsim.
Daim duab 01: Ribozyme Action
Tsis tas li ntawd, ribozymes ua ib feem ntawm lub subunit loj ntawm ribosomes thiab koom nrog cov dej num ntawm protein synthesis xws li RNA splicing, tRNA synthesis, thiab lwm yam. Hammerhead ribozyme, Varkud satellite (VS) ribozyme, Leadzyme thiab hairpin ribozyme yog ob peb piv txwv ntawm ribozymes.
YNtaus Protein Enzymes yog dab tsi?
Protein enzymes yog cov khoom siv roj ntsha uas ua rau cov tshuaj lom neeg feem ntau tshwm sim hauv cov nroj tsuag, tsiaj txhu, kab mob thiab lwm yam kab mob. Feem ntau, thaum tsis muaj enzymes, feem ntau ntawm cov tshuaj biochemical pom tau tias qeeb heev. Yog li ntawd, enzymes yog ib qho tseem ceeb biomolecules nyob rau hauv tag nrho cov muaj sia nyob. Raws li txoj cai, enzymes yog tsim los ntawm cov amino acid sequences. Li no, lawv yog cov proteins tshwj xeeb.
Function
Enzymes nrawm cov tshuaj tiv thaiv los ntawm kev khi nrog cov substrate los ntawm lawv qhov chaw catalytic. Tsis tas li ntawd, cov enzymes tshwj xeeb rau lawv cov substrates. Ntau zaus, cov duab ntawm qhov chaw catalytic yog ntxiv rau cov duab ntawm cov substrates. Yog li ntawd, ib hom enzymes tuaj yeem tswj tau qee hom kev tshwm sim. Yog li ntawd, muaj ntau hom enzymes nyob rau hauv lub hlwb. Amylase, m altase, trypsin, protease, pepsin, lipase, polymerase, cellulase, cawv dehydrogenase, sucrase thiab lactase yog ib co piv txwv rau enzymes.
Daim duab 02: Enzymes
Txhua enzyme ua haujlwm zoo tshaj plaws ntawm nws qhov ntsuas kub thiab pH. Yog li ntawd, peb yuav tsum muab cov kev mob zoo tshaj plaws thaum muaj kev cuam tshuam. Yog tias qhov kub siab tshaj qhov ntsuas kub ntawm cov proteins, cov duab ntawm cov enzymes yuav hloov thiab lawv cov dej num yuav raug kaw. Thaum kawg, tus nqi ntawm cov tshuaj tiv thaiv ua qeeb. Yog tias cov enzyme ua haujlwm ntawm ib txwm muaj, nws tseem tsis hloov pauv txawm tias tom qab cov tshuaj tiv thaiv. Li no, nws tuaj yeem koom nrog lwm cov tshuaj tiv thaiv. Qee cov enzymes xav tau cofactors rau kev ua haujlwm. Cofactors yog inorganic lossis organic molecules. Lawv pab enzymes los ntawm kev khi nrog cov enzyme loosely los yog nruj nreem.
Dab tsi zoo sib xws ntawm Ribozymes thiab Protein Enzymes?
- Ob leeg ribozymes thiab protein enzymes yog cov khoom siv roj ntsha.
- Lawv muaj peev xwm catalyzing biochemical tshuaj uas tshwm sim hauv cov kab mob nyob.
- Tsis tas li, ob leeg yog macromolecules.
- Dhau li ntawm, lawv muaj ntau yam qauv thiab cov txheej txheem.
Qhov txawv ntawm Ribozymes thiab Protein Enzymes yog dab tsi?
Qhov sib txawv tseem ceeb ntawm ribozymes thiab protein enzymes yog tias ribozymes yog RNA molecules thaum protein enzymes yog globular proteins. Yog li ntawd, ribozymes yog polymers ntawm ribonucleotides thaum protein enzymes yog polymers ntawm amino acids. Yog li, qhov no kuj yog qhov sib txawv ntawm ribozymes thiab protein enzymes.
Ntxiv mus, qhov sib txawv ntxiv ntawm ribozymes thiab protein enzymes yog tias cov ribozymes muaj nyob rau hauv ribosomes thaum cov protein enzymes muaj nyob txhua qhov chaw hauv cell txawm nyob rau hauv ntau lub cell organelles.
Cov duab hauv qab no qhia cov ntsiab lus ntxiv ntawm qhov sib txawv ntawm ribozymes thiab protein enzymes.
Summary – Ribozymes vs Protein Enzymes
Ribozymes thiab protein enzymes yog ob hom kab mob lom uas muaj nyob hauv cov hlwb. Lawv ua ib yam nkaus. Txawm li cas los xij, ribozymes yog RNA molecules tsim los ntawm ribonucleotides thaum protein enzymes yog globular proteins uas muaj cov amino acids. Tsis tas li ntawd, ribozymes muaj nyob rau hauv ribosomes thaum cov protein enzymes muaj nyob txhua qhov chaw hauv lub cell. Tsis tas li ntawd, ribozymes muaj tsawg dua thaum cov protein enzymes muaj ntau dua hauv cell. Yog li, qhov no yog cov ntsiab lus ntawm qhov sib txawv ntawm ribozymes thiab protein enzymes.
