Chii chinonzi mitochondrial matrix?
Mu mitochondrion, matrix inzvimbo iri mukati memembrane yomukati. Shoko rokuti "matrix" rinobva pakuti nzvimbo iyi ine viscous, kana ichienzaniswa necytoplasm ine mvura. Mitochondrial matrix ine mitochondrial DNA, ribosomes, soluble enzymes, zviduku organic molecules, nucleotide cofactors, uye inorganic ions. Maenzayimu ari mumatrix anobatsira kuita zvinhu zvinogadzira ATP, zvakadai sokugadzirwa kwecitric acid, oxidative phosphorylation, oxidation ye pyruvate, uye beta oxidation yemafuta acids.  Kuumbwa kwematrix kwakavakirwa pazvimiro zvayo nezviri mukati kunogadzira mhoteredzo inobvumira nzira dzeanabolic nedze catabolic kuti dzifambire mberi zvakanaka. Electron transport chain nema enzymes ari mumatrix anoita basa guru mu citric acid cycle uye oxidative phosphorylation. The citric acid cycle inogadzira NADH uye FADH2 kuburikidza ne oxidation iyo ichaderedzwa mu oxidative phosphorylation kugadzira ATP.  Mvura inowanikwa muchitokisi checytosol, ine mvura inenge 3.8 μL/mg yeprotein, nepo iri muchitokisi chemitochondrial ine mvura inenge 0.8 μL/mg yeprotein. Hazvizivikanwi kuti mitochondria inochengetedza sei osmotic balance mukati memukati memitochondrial membrane, kunyange zvazvo membrane iine aquaporins iyo inofungidzirwa kuti inochengetedza kutakura kwemvura. Mitochondrial matrix ine pH yeinenge 7.8, iyo yakakwirira kudarika pH yenzvimbo yepakati pemembrane yemitochondria, iyo inenge 7.0<unk>7.4. Mitochondrial DNA yakawanwa naNash naMargit muna 1963. DNA ine tambo mbiri inenge imwe chete kana kuti dzakawanda inenge yakatenderera inowanikwa mumitochondrial matrix. Mitochondrial DNA i1% yeDNA yose yesero. Iyo yakapfuma mu guanine uye cytosine zviri mukati. Mitochondria yezvipembenene ine 55s ribosomes.
