Cov ob theem ntawm photosynthesis : Photosynthesis siv qhov chaw hauv ob theem: lub teeb-nyob ntawm cov tshuaj tiv thaiv thiab Calvin lub voj voog (lub teeb-yeeb yaj kiab). Lub teeb-dependent tshuaj tiv thaiv, uas coj qhov chaw nyob rau hauv thylakoid daim nyias nyias, siv lub teeb lub zog los ua ATP thiab NADPH.

Ib yam li ntawd, koj tuaj yeem nug, Phase 1 ntawm photosynthesis tshwm sim nyob qhov twg?

Theem Ib : Lub teeb Reactions Nyob rau hauv lub teeb-dependent txheej txheem, uas yuav siv sij hawm qhov chaw nyob rau hauv lub grana, lub stacked membrane qauv nyob rau hauv chloroplasts, lub zog ncaj qha ntawm lub teeb pab cov nroj tsuag ua molecules uas nqa lub zog rau kev siv nyob rau hauv qhov tsaus ntuj nti. theem ntawm photosynthesis.

Ib tug kuj yuav nug, dab tsi yog peb theem ntawm photosynthesis thiab lawv tshwm sim qhov twg? Nws yog qhov yooj yim los faib cov photosynthetic txheej txheem hauv cov nroj tsuag ua plaub theem , cwb tshwm sim nyob rau hauv ib cheeb tsam ntawm chloroplast: (1) nqus lub teeb, (2) electron thauj mus rau qhov txo ntawm NADP+ rau NADPH, ( 3 ) tiam ntawm ATP, thiab (4) kev hloov pauv ntawm CO2 nyob rau hauv carbohydrates (carbon fixation).

Ib sab ntawm no, qhov thib ob theem ntawm photosynthesis tshwm sim?

Cov theem ob ntawm photosynthesis tshwm sim nyob rau hauv lub stroma nyob ib ncig ntawm lub thylakoid daim nyias nyias ntawm chloroplast. Cov tshuaj tiv thaiv ntawm no theem tuaj yeem tshwm sim tsis muaj lub teeb, yog li lawv qee zaum hu ua lub teeb-yooj yim lossis tsaus ntuj.

Photosystem 1 thiab 2 nyob qhov twg?

Photosystems yog pom nyob rau hauv thylakoid daim nyias nyias ntawm cov nroj tsuag, algae thiab cyanobacteria. Lawv yog nyob nyob rau hauv chloroplasts ntawm cov nroj tsuag thiab algae, thiab nyob rau hauv lub cytoplasmic membrane ntawm photosynthetic kab mob. Muaj ob hom kev yees duab : II i.
