Teb thiab piav qhia: Lub theem ob ntawm photosynthesis suav nrog cov pa roj carbon fixation thiab hu ua cov tshuaj tiv thaiv tsaus nti, lossis Calvin voj voog. Photosynthesis pib nrog thawj theem , hu ua lub teeb pom kev zoo. Ntawm no, lub zog los ntawm tshav ntuj raug sau thiab hloov mus rau hauv tshuaj lom neeg lub zog hauv daim ntawv ntawm NADPH thiab ATP.

Tsuas yog li ntawd, dab tsi yog tsim nyob rau hauv theem ob ntawm photosynthesis?

Cov theem ob ntawm photosynthesis yog cov ntau lawm cov piam thaj los ntawm carbon dioxide. Cov txheej txheem no tshwm sim nyob rau hauv ib tug tas mus li voj voog, muaj npe tom qab nws nrhiav tau, Melvin Calvin. Lub voj voog Calvin siv CO2 thiab lub zog ib ntus khaws cia hauv ATP thiab NADPH los ua kom cov piam thaj qab zib.

Tsis tas li ntawd, 2 hom photosynthesis yog dab tsi? Muaj ob hom photosynthetic txheej txheem: oxygenic photosynthesis thiab anoxygenic photosynthesis . Cov ntsiab cai dav dav ntawm anoxygenic thiab oxygenic photosynthesis zoo sib xws, tab sis oxygenic photosynthesis Nws yog feem ntau pom nyob rau hauv cov nroj tsuag, algae thiab cyanobacteria.

Ib yam li ntawd, qhov thib ob theem ntawm photosynthesis tshwm sim?

Lub teeb-dependent cov tshuaj tiv thaiv coj qhov chaw nyob rau hauv thylakoid daim nyias nyias nyob rau hauv lub granum (pawg ntawm thylakoids), nyob rau hauv lub chloroplast. Ob tug theem ntawm photosynthesis : Photosynthesis tshwm sim nyob rau hauv ob theem : Lub teeb-dependent cov tshuaj tiv thaiv thiab Calvin lub voj voog (light-independent reactions).

Dab tsi yog theem ntawm photosynthesis?

Nws yog qhov yooj yim los faib cov photosynthetic txheej txheem hauv cov nroj tsuag ua plaub theem , txhua qhov tshwm sim nyob rau hauv ib cheeb tsam ntawm chloroplast: (1) nqus ntawm 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).
