Matrix ea mitochondrial ke eng?
Ka har'a mitochondrion, matrix ke sebaka se ka har'a lera le ka hare. Lentsoe "matrix" le tsoa ntlheng ea hore sebaka sena se na le viscous, ha se bapisoa le cytoplasm e nang le metsi. Matrix ea mitochondrial e na le DNA ea mitochondrial, li-ribosome, li-enzyme tse qhibilihang, limolek'hule tse nyenyane tsa manyolo, li-cofactors tsa nucleotide le li-ion tse sa tloaelehang. Li - enzyme tse ka har'a matrix li thusa ho etsa liphetoho tse ikarabellang bakeng sa ho hlahisa ATP, tse kang potoloho ea asiti ea citric, phosphorylation ea oxidative, oxidation ea pyruvate le beta oxidation ea mafura acid.  Ho hlophisoa ha matrix ho itšetlehile ka mehaho ea eona le lintho tse ka hare ho eona ho hlahisa tikoloho e lumellang litsela tsa anabolic le tsa catabolic hore li tsoele pele hantle. Ketane ea ho tsamaisa lielektrone le li-enzyme tse matrix li bapala karolo e kholo potolohong ea asiti ea citric le phosphorylation ea oxidative. Potoloho ea asiti ea citric e hlahisa NADH le FADH2 ka oxidation e tla fokotsoa ka phosphorylation ea oxidative ho hlahisa ATP.  Sebaka sa li-cytosol, se pakeng tsa li-membrane, se na le metsi a etsang 3.8 μL/mg ea protheine, ha motsoako oa mitochondrial e le 0.8 μL/mg ea protheine. Ha ho tsejoe hore na mitochondria e boloka botsitso ba osmotic joang ka har'a lera la mitochondrial le kahare, leha lera lena le na le li-aquaporins tseo ho lumeloang hore ke lipeipi tsa lipalangoang tsa metsi tse laoloang. Mitochondrial matrix e na le pH ea hoo e ka bang 7.8, e leng e phahameng ho feta pH ea sebaka se pakeng tsa mitochondria, e ka bang 7.0<unk>7.4. Mitochondrial DNA e ile ea sibolloa ke Nash le Margit ka 1963. DNA e le 'ngoe ho isa ho e mengata e nang le likhoele tse peli e teng ka har'a mitochondrial matrix. DNA ea mitochondrial ke 1% ea DNA eohle ea sele. E na le guanine le cytosine e ngata. Mitochondria ea liphoofolo tse anyesang e na le li-ribosome tse 55s.
