rubisco. Contraction ntawm ribulose bisphosphate carboxylase / oxygenase, lub enzyme uas ua ke carbon dioxide lossisoxygen nrog ribulose bisphosphate rau catalyze thawj kauj ruam ntawm photosynthetic carbon fixation lossis photorespiration, feem.
RuBisCO siv dab tsi ua substrate?
Rubisco tau lees paub dav raws li qhov kawg ntawm tus nqi txwv cov kauj ruam hauv photosynthetic carbon fixation. Atmospheric oxygen sib tw nrog CO2 ua ib lub substrate rau Rubisco, ua rau kom photorespiration.
Dab tsi yog substrate rau photorespiration?
Respiratory substrate hauv photorespiration yog a 2-carbon compound glycolic acid (2C), li no hu ua C, cycle.
RuBisCO siv dab tsi hauv photorespiration?
Photorespiration hauv Green Leaves
Nyob rau hauv Calvin lub voj voog ntawm photosynthesis, bifunctional chloroplast enzyme ribulose-1, 5-bisphosphate carboxylase /oxygenase (RubisCO) siv nws cov carboxylase kev ua kom muaj txiaj ntsig txuas CO 2 rau 5-carbon substrate, ribulose-1, 5-bisphosphate.
Dab tsi yog cov substrates ntawm RuBisCO thaum lub sijhawm photosynthesis?
RuBisCO yuav tsum xub qhib los ntawm carbamylation thiab khi ntawm Mg2+ ua ntej nws ua peb substrates, ribulose bisphosphate (RuBP), thiab carbon dioxide lossis oxygen., cov kev tawm tsam ua tiav tau tshwm sim ntau theem (Lorimer, 1981; Cleland li al., 1998; Andersson, 2008; Kannappan thiab Gready, 2008).
