Starch yog tsim los ntawm plaub qhov kev cog lus enzyme: ADP-Glc pyrophosphorylase, uas ua rau cov piam thaj nucleotide precursors; starch synthase, uas txuas ntxiv alpha-1, 4-txuas glucan chains siv ADP-Glc; starch-branching enzymes, uas qhia alpha-1, 6 ceg ntsiab lus los tsim amylopectin; thiab starch debranching…
Cov hmoov txhuv nplej siab ua los ntawm cov piam thaj li cas?
YBiosynthesis. Cov nroj tsuag tsim cov hmoov txhuv nplej siab los ntawm
ua ntej hloov cov piam thaj 1-phosphate rau ADP-glucose siv cov enzyme glucose-1-phosphate adenylyltransferase … Cov enzyme starch synthase ces ntxiv ADP-glucose ntawm 1, 4- alpha glycosidic daim ntawv cog lus rau cov saw hlau loj hlob ntawm cov piam thaj seem, tso tawm ADP thiab tsim amylose.
txhais li cas los ua cov hmoov txhuv nplej siab?
Cov qauv thiab kev sib txuas ntawm cov hmoov txhuv nplej siab
Starch, cov carbohydrates nyuaj, yog a polymer ntawm qabzib molecules… ADP-glucose pyrophosphorylase (AGPase), uas catalyses cov tshuaj tiv thaiv ntawm qabzib-1-phosphate nrog ATP los tsim ADP-glucose (liberating pyrophosphate).
YPuas yog hmoov txhuv nplej siab thaum lub sij hawm photosynthesis?
Cov hmoov txhuv nplej siab uas tau tsim nyob rau hauv nplooj ncaj qha los ntawm photosynthates thaum nruab hnub feem ntau txhais tau tias yog hloov cov hmoov txhuv nplej siab, vim nws tau degraded nyob rau hmo tom ntej kom txhawb nqa cov metabolism, lub zog tsim khoom. thiab biosynthesis thaum tsis muaj photosynthesis.
Yuav ua li cas cov hmoov txhuv nplej siab tau tswj hwm?
Txoj cai ntawm STARCH BIOSYNTHESIS IN RESPONSE TO SUGAR SIGNALS Txhim kho lub teeb / tsaus ntuj tseem yuav ua rau muaj kev hloov pauv hauv cov pa roj carbon ntau. sib npaug ntawm cov nroj tsuag. … Nyob rau hauv nplooj, kev tswj cov piam thaj-dependent tso cai rau cov hmoov txhuv nplej siab synthesis txuas mus rau photosynthetic kev ua si thiab carbon export nqi rau cov ntaub so ntswg loj hlob.
