Vim li cas cov cab kuj xav tau rau kev thauj cov electrons Los ntawm ib feem ntawm chloroplast mus rau lwm qhov? Siab zog electrons txav mus los ntawm electron thauj saw hlau. Pigments hauv Photosystem II nqus lub teeb. ATP synthase tso cai rau H + ions dhau los ntawm thylakoid membrane.

Ntxiv mus, dab tsi ua rau ib tug zoo electron cab kuj?

Lawv txais tau electrons thiab hloov feem ntau ntawm lawv lub zog mus rau lwm lub molecule. Lawv yog cov molecules loj heev, yog li lawv muaj ntau chav rau nqa ntau electrons . Lawv tuaj yeem nqus tau lub hnub ci, uas yog qhov chaw tag nrho ntawm lub zog siab electrons los ntawm.

Ib yam li ntawd, dab tsi yog cov khoom siv hluav taws xob hauv cellular respiration? Muaj ob lub tshuab nqa hluav taws xob uas ua lub luag haujlwm tseem ceeb thaum lub sij hawm ua pa ntawm tes: NAD + ( nicotinamide adenine dinucleotide yog tsim los ntawm nicotinamide , qhia hauv qab no) thiab FAD (flavin adenine dinucleotide).

Ntawm no, cov khoom siv hluav taws xob yog dab tsi thiab lawv ua dab tsi tshwj xeeb?

Ib electron cab kuj yog molecule uas thauj electrons thaum ua pa ntawm tes. NAD yog ib electron cab kuj siv los khaws lub zog ib ntus thaum lub sijhawm ua pa ntawm tes. Lub zog no yog khaws cia los ntawm kev txo cov tshuaj tiv thaiv NAD + + 2H NADH + H +.

Lub luag haujlwm ntawm electron carrier molecules hauv lub zog ua haujlwm yog dab tsi?

Electron cab kuj molecules ua raws li lawv lub npe hais. Lawv nqa electrons los ntawm ib feem ntawm ib qho zog ua system rau lwm tus, muab qhov tsim nyog zog thiab txo hwj chim ua kom muaj tshuaj lom neeg tshwm sim.
