Qhov sib txawv tseem ceeb ntawm chemiluminescence thiab bioluminescence yog tias chemiluminescence yog tsim thiab emission ntawm lub teeb vim tshuaj lom neeg cov tshuaj tiv thaiv, thaum bioluminescence yog tsim thiab emission ntawm lub teeb vim biochemical tshua los ntawm cov kab mob nyob.
Luminescence yog qhov tshwm sim ntawm qhov tshwm sim tshwm sim ntawm lub teeb los ntawm ib yam khoom. Nws yog ib daim ntawv ntawm lub cev txias. Nws tuaj yeem yog qhov tshwm sim ntawm cov tshuaj tiv thaiv, hluav taws xob hluav taws xob, cov lus tsa suab subatomic, lossis kev ntxhov siab ntawm lub pob zeb. Muaj ntau hom luminescence, xws li chemiluminescence, bioluminescence, electrochemiluminescence, lyoluminescence, candoluminescence, crystalloluminescence, electroluminescence, cathodoluminescence, mechanoluminescence, sonoluminescence, photoluminescence, fluorescence, thermospholuminescence, radioluminescence
Chemiluminescence yog dab tsi?
Chemiluminescence txhais tau tias yog lub teeb tawm los ntawm cov tshuaj tiv thaiv tshuaj. Chemiluminescence tseem hu ua chemoluminescence. Ntxiv nrog rau lub teeb, tshav kub kuj tuaj yeem tsim los ntawm cov tshuaj tiv thaiv chemiluminescent, uas ua rau cov tshuaj tiv thaiv exothermic. Ib qho piv txwv classic ntawm chemiluminescence yog cov tshuaj tiv thaiv luminol pom hauv chemistry. Hauv cov tshuaj tiv thaiv no, luminol reacts nrog H2O2 (hydrogen peroxide) kom tso lub teeb xiav. Tus nqi ntawm lub teeb tso tawm los ntawm cov tshuaj tiv thaiv no tsawg heev tshwj tsis yog tias ib qho me me ntawm qhov tsim nyog catalyst ntxiv. Cov catalyst raug rau cov tshuaj tiv thaiv chemiluminescent no yog ib qho me me ntawm cov hlau lossis tooj liab.

Ib qho piv txwv zoo ntawm chemiluminescence yog cov tshuaj tiv thaiv uas ib txwm tshwm sim hauv cov nplaum nplaum. Ntawm no, cov xim ntawm cov nplaum nplaum yog qhov tshwm sim ntawm cov xim fluorescent uas absorbs lub teeb los ntawm chemiluminescence thiab tso tawm ua lwm yam xim. Tsis tas li ntawd, yam xws li kub cuam tshuam chemiluminescence. Yog li ntawd, nce qhov kub ntawm cov tshuaj tiv thaiv chemiluminescent ua rau nws tso lub teeb ntau dua. Cov nyhuv no tuaj yeem pom tau yooj yim siv cov nplaum nplaum. Muab ib daim nplaum nplaum rau hauv dej kub ua rau nws ci ntsa iab. Txawm li cas los xij, lub teeb no tsis kav ntev li.
YBioluminescence yog dab tsi?
Bioluminescence yog qhov tshwm sim cuam tshuam nrog kev tsim khoom thiab emission ntawm lub teeb vim muaj kev cuam tshuam biochemical los ntawm cov kab mob nyob. Nws tshwm sim hauv cov kab mob muaj sia xws li fireflies, qee cov fungi, ntau cov tsiaj hauv hiav txwv, thiab qee cov kab mob. Nws tsis feem ntau tshwm sim hauv cov nroj tsuag tshwj tsis yog tias lawv cuam tshuam nrog cov kab mob bioluminescent. Tsiaj txhu feem ntau ci vim lawv txoj kev sib raug zoo nrog cov kab mob Vibrio.
Daim duab 02: Bioluminescence
Bioluminescence feem ntau tshwm sim los ntawm cov tshuaj tiv thaiv ntawm cov enzyme luciferase thiab luminescent pigment luciferin. Cov protein zoo li aequorin thiab cofactors xws li calcium lossis magnesium tuaj yeem pab cov tshuaj tiv thaiv. Cov tshuaj tiv thaiv xav tau lub zog nkag, uas feem ntau tau txais los ntawm ATP. Muaj qhov sib txawv me ntsis ntawm luciferins los ntawm ntau hom. Txawm li cas los xij, luciferase enzyme sib txawv heev ntawm phyla. Ntsuab thiab xiav bioluminescence feem ntau yog. Qee hom emit liab bioluminescence ib yam nkaus. Cov kab mob siv bioluminescence rau ntau lub hom phiaj, suav nrog cov tsiaj nyeg, luring, ceeb toom, phooj ywg saib xyuas, camouflage, thiab illuminating lawv ib puag ncig.
Dab tsi yog qhov zoo sib xws ntawm Chemiluminescence thiab Bioluminescence?
- Chemiluminescence thiab bioluminescence yog ob hom luminescence.
- Ob qhov kev cuam tshuam tsim lub teeb los ntawm cov khoom tsis muaj cua sov.
- Ob qhov kev cuam tshuam yog catalyzed los ntawm ntau yam catalysts.
- Tus nqi ntawm lub teeb uas tsim los ntawm ob qho tib si cuam tshuam los yog cuam tshuam los ntawm ntau yam.
Qhov txawv ntawm Chemiluminescence thiab Bioluminescence yog dab tsi?
Chemiluminescence yog tsim thiab emission ntawm lub teeb vim tshuaj lom neeg cov tshuaj tiv thaiv, thaum bioluminescence yog tsim thiab emission ntawm lub teeb vim biochemical cov tshuaj tiv thaiv los ntawm cov kab mob nyob. Qhov no yog qhov sib txawv tseem ceeb ntawm chemiluminescence thiab bioluminescence. Tsis tas li ntawd, chemiluminescence yog cov txheej txheem tshuaj tiv thaiv catalysed los ntawm inorganic catalysts, thaum bioluminescence yog cov txheej txheem tshuaj tiv thaiv catalysed los ntawm enzymes.
Cov lus hauv qab no qhia txog qhov sib txawv ntawm chemiluminescence thiab bioluminescence.
Summary – Chemiluminescence vs Bioluminescence
Luminescence yog cov txheej txheem ntawm qhov tshwm sim ntawm lub teeb los ntawm ib yam khoom. Chemiluminescence thiab bioluminescence yog ob hom luminescence. Chemiluminescence yog tsim thiab emission ntawm lub teeb vim tshuaj lom neeg cov tshuaj tiv thaiv, thaum bioluminescence yog zus tau tej cov thiab emission ntawm lub teeb vim biochemical tshuaj los ntawm cov kab mob nyob. Qhov no yog qhov sib txawv tseem ceeb ntawm chemiluminescence thiab bioluminescence.
