Lub teeb xiav: Lub nqus tau tus nqi yuav txo Thaum lub sij hawm lub teeb xiav yog absorbed carotenoids thiab chlorophyll b rau photosynthesis . Yog li DCPI yuav txo qis thiab hloov ntawm xiav mus rau tsis muaj xim nyob rau lub sijhawm.
Ib yam li ntawd, absorbance cuam tshuam li cas rau photosynthesis?
Pigments nqus lub teeb siv hauv photosynthesis . Hloov chaw, photosynthetic Cov kab mob muaj lub teeb-absorbing molecules hu ua pigments uas nqus cov wavelengths tshwj xeeb ntawm lub teeb pom kev, thaum xav txog lwm tus. Cov txheej ntawm wavelengths absorbed los ntawm ib tug pigment yog nws nqus spectrum.
Qhov thib ob, qhov absorbance ntawm DPIP hloov li cas thaum nws raug txo? LabBench Activity Thaum lub teeb tawm tsam cov chloroplasts, lub DPIP yog txo los ntawm kev zoo siab electrons los ntawm chlorophyll, thiab nws kev hloov los ntawm nws thawj xim xiav rau xim tsis muaj xim raws li nws txais cov electrons.
Cov lus nug tseem yog, Dcpip txo qis hauv photosynthesis li cas?
Thaum raug lub teeb nyob rau hauv ib photosynthetic system, cov dye yog decolorised los ntawm tshuaj txo. DCPIP muaj affinity ntau dua rau electrons tshaj ferredoxin thiab cov photosynthetic electron thauj saw tau txo DCPIP raws li kev hloov pauv rau NADP+, uas feem ntau yog qhov kawg electron cab kuj nyob rau hauv photosynthesis.
Vim li cas ammonium hydroxide cuam tshuam rau photosynthesis?
Ammonium hydroxide tau qeeb electron hloov mus rau electron thauj saw mus rau DCPIP. Ammonium hydroxide txais electrons thiab ua tsis dhau electrons raws li electron thauj saw mus rau DCPIP. Qee cov tshuaj tua kab yog cov tshuaj uas lees txais electrons thaum lub sijhawm photosynthesis.

Vim li cas qhov pib txo qis nrog qhov loj?
Lub hauv paus txo qis thaum ib tus mus rau hauv pawg hauv lub rooj sib tham nrog cov ntsiab lus, vim tias qhov loj ntawm atoms nce mus rau hauv pawg. Kev piav qhia: Thiab yog li ntawd lub cim xim hlau ntawm lub atom nce thiab ces qhov pib txo qis
NADP txo qis hauv cov tshuaj tiv thaiv lub teeb li cas?
Tsis yog-Cyclic Photophosphorylation Cov electrons los ntawm PS I kuj tseem tuaj yeem dhau mus rau cov khoom siv hluav taws xob thiab tom qab ntawd ua ke nrog hydrogen ions (los ntawm dej) kom txo NADP rau NADPH. Qhov kev txo qis NADP no yog siv rau hauv cov tshuaj tiv thaiv tom ntej
Yuav txo qis hauv kev tshawb fawb li cas?
Txhawm rau txo qhov siab - txo qhov quab yuam los yog ua kom thaj tsam qhov quab yuam ua rau. Yog tias koj tau sawv ntawm lub pas dej khov thiab cov dej khov pib tawg koj tuaj yeem pw tsaug zog kom thaj chaw sib cuag nrog cov dej khov. Tib lub zog (koj qhov hnyav) yuav siv tau, kis mus rau thaj chaw loj dua, yog li lub siab yuav txo
Vim li cas lub hauv paus ntawm hydrides txo qis hauv pab pawg?
Vim lub xub ntiag ntawm ib leeg khub ntawm electron, cov hydrides ntawm cov ntsiab lus yog qhov yooj yim (Lewis bases) nyob rau hauv qhov. Lub hauv paus tseem ceeb txo qis nrog qhov loj ntawm lub hauv paus atom vim diffusion ntawm electrons tshaj qhov ntim loj piv txwv li hauv cov pab pawg, raws li qhov loj ntawm cov ntsiab lus tsub kom cov electron ceev ntawm lub ntsiab txo
Vim li cas qhov kev tso tawm nce qis qis?
Ob qhov dav thiab qhov tob nce qis qis vim qhov tso tawm nce qis qis. Raws li kev tso tawm tsub kom tus ntoo khaub lig cov duab yuav hloov, nrog cov kwj deg ua tob thiab dav
