Photosystem I thiab photosystem II yog ob lub complexes multi-protein uas muaj cov pigments tsim nyog los sau cov photons thiab siv lub teeb lub zog los catalyze thawj photosynthetic endergonic cov tshuaj tiv thaiv uas ua rau muaj zog sib txuas.

Ib yam li ntawd, tib neeg nug, dab tsi yog qee qhov haujlwm ntawm photosystem I thiab photosystem II hauv cov nroj tsuag?

Photosystem II ua haujlwm nrog Photosystem Kuv thiab ob series ntawm enzymes imbedded nyob rau hauv lub thylakoid membrane kom hloov lub zog los ntawm daim ntawv ntawm lub teeb mus rau uas khaws cia nyob rau hauv tshuaj bands thiab gradients uas lub cog tuaj yeem siv hauv cov txheej txheem hu ua noncyclic photophosphorylation.

Lub luag haujlwm ntawm photosystem II yog dab tsi? Photosystem II (PSII) yog ib qho tshwj xeeb protein complex uas siv lub teeb zog los tsav kev hloov ntawm electrons los ntawm dej mus rau plastoquinone, ua rau zus tau tej cov pa thiab tso tawm ntawm plastoquinone txo mus rau hauv lub photosynthetic membrane.

Hauv qhov no, lub luag haujlwm ntawm photosystem 1 thiab 2 yog dab tsi?

Qhov tseem ceeb muaj nuj nqi ntawm kev yees duab Kuv nyob hauv NADPH synthesis, qhov twg nws tau txais cov electrons los ntawm PS II . Qhov tseem ceeb muaj nuj nqi ntawm photosystem II yog nyob rau hauv hydrolysis ntawm dej thiab ATP synthesis. PSI yog tsim los ntawm ob lub subunits uas yog psaA thiab psaB.

Tus qauv thiab kev ua haujlwm ntawm photosystem yog dab tsi?

Photosystem kuv, a daim nyias nyias protein complex pom nyob rau hauv tag nrho cov oxygenic photosynthetic kab mob, siv lub teeb lub zog los hloov electrons los ntawm plastocyanin rau ferredoxin. Lub teeb lub zog ntes los ntawm kav hlau txais xov chlorophylls yog xa mus sai sai rau tus thawj electron pub, P700.
