Carotenoids yog ubiquitous thiab tseem ceeb pigments nyob rau hauv photosynthesis Lawv nqus nyob rau hauv xiav-ntsuab thaj tsam ntawm lub hnub ci spectrum thiab hloov lub absorbed zog rau (bacterio-) chlorophylls, thiab thiaj li nthuav. lub wavelength ntau ntawm lub teeb uas muaj peev xwm tsav photosynthesis.
2 lub luag haujlwm ntawm carotenoids yog dab tsi?
Carotenoids tau pom tias muaj ob lub luag haujlwm tseem ceeb hauv photosynthesis. Lawv ua raws li photoprotective agents, tiv thaiv cov teeb meem photodynamic cov tshuaj tiv thaiv, thiab raws li accessory light-sharvesting pigments, txuas cov spectral ntau yam uas lub teeb drives photosynthesis.
YPuas carotene ua photosynthesis?
Carotenes pab rau photosynthesis los ntawm kev xa lub teeb lub zog lawv nqus mus rau chlorophyll Lawv kuj tiv thaiv cov ntaub so ntswg los ntawm kev pab nqus lub zog los ntawm singlet oxygen, ib daim ntawv zoo siab ntawm oxygen molecule O2 uas yog tsim thaum lub sij hawm photosynthesis.
ua li cas carotenoids pab hauv cov txheej txheem photosynthetic?
ua li cas carotenoids pab hauv cov txheej txheem photosynthetic? Lawv ua raws li cov xim tiv thaiv uas tiv thaiv cov khoom siv hluav taws xob thiab tiv thaiv cov tshuaj dawbLawv tiv thaiv kev tsim cov pa oxygen reactive los ntawm UV irradiation. Sau cov electrons los pub rau chlorophyll accessories rau photosynthesis.
Puas carotenoid pigments pab cov nroj tsuag thaum lub sij hawm photosynthesis?
Cov kws tshawb fawb tau pom tias lawv kuj pab sau lub teeb lub zog thaum lub sijhawm photosynthesis. Carotenoids, tib cov pigments uas muab cov txiv kab ntxwv xim rau carrots thiab liab rau txiv lws suav, feem ntau pom ua ke nyob rau hauv cov nroj tsuag nrog chlorophyll pigments uas sau hnub ci zog.
