Glycolysis - e ... 'Me lintho tsa motheo tsa tsoekere ho kena moea

A sehloohong sena a re hlahlobeng ka ho qaqileng aerobiki glycolysis, dithulaganyo tsa lona, sekaseka ho ba sethaleng le mekhahlelo. A look at the anaerobic ho kena moea oa tsoekere, ithuta ka diphetolo ho iphetola ha lintho tsa tshebetso le lekanya bohlokoa tsa lona tsa likokoana-hloko.

glycolysis ke eng

Glycolysis - ke e 'ngoe ea mefuta e meraro ea thulaganyou e ho kena moea tsoekere moo thulaganyou e ho kena moea ka boeona e tsamaea le ho lokolloa ha matla, e leng e bolokwa ka NADH le ATP. Ka tshebetso ya ho glycolysis tloha tsoekere molek'hule hlahiswa limolek'hule tse peli tsa acid e pyruvic.

Glycolysis - tšebetso e le hore ho etsahala tlas'a tšusumetso ea ho etswa ha tse fapa-fapaneng tsa likokoana-hloko - enzyme. The oxidant ka sehloohong ke oksijene - O ₂ Leha _ho le joalo, le thulaganyo ya glycolysis ka tsoela pele ka ho ba sieo ha eona. mofuta ona o bitsoa glycolysis - anaerobic glycolysis.

Glycolysis baprocedure ho ba sieo ha oksijene

Anaerobic glycolysis - tsoekere sethaleng ho kena moea a thulaganyo eo tsoekere e sa ka botlalo oxidized. Ho bopa molek'hule e 'ngoe ea acid e pyruvic. Le ka ho ya ka matla, glycolysis sieo ha oksijene (anaerobic) e sa sebetsa. Leha ho le joalo, kenoa oksijene ka seleng e anaerobic thulaganyou e ho kena moea ka sokolohela aerobiki le phalla ka foromo ka botlalo.

mekgwa ya glycolysis

Tshebetso ya ho glycolysis - e tšeletseng k'habone tsoekere li bole kapele pyruvate ka tse peli limolek'hule tse tharo-k'habone. Tsela ena ka boeona e arotsoe ka mekhahlelo e 5 ea ho lokisetsa le mekhahlelo e 5, eo ho eona matla a bolokoa ATP.

Tsela ea mekhahlelo glycolysis 2 le mekhahlelo e 10 ke tse latelang:

• Sethaleng 1, sethaleng 1 - tsoekere phosphorylation. Ho ea ka botšelela k'habone athomo ea tsoekere ka boeona saccharide e butswe ka phosphorylation.
• Mohato oa 2 - Isomerization ya tsoekere-6-phosphate. Mothating ona catalytic fosfoglyukozoimeraza hulela tsoekere ka fructose-6-phosphate.
• Mohato 3 - Fructose-6-phosphate le phosphorylation lona. mohato Sena ke sebōpeho sa fructose-1.6-diphosphate (aldolase) ke ketso ea phosphofructokinase-1, e tsamaea le phosphoryl sehlopha tloha diphosphate adenosine ho molek'hule oa fructose.
• Mohato 4 - ke tshebetso ya ho petsoha le aldolase ya ho theha ba babeli phosphate limolek'hule triose, e leng eldozy le ketose.
• Mohato 5 - triose le isomerization. Mothating ona, glyceraldehyde 3-phosphate e romeloa ho mehato e ileng ea latela ya petsoha tsoekere le dihydroxyacetone phosphate tsoela ka mokgwa wa glyceraldehyde-3-phosphate ke potlakisang tsebetso ea lik'hemik'hale le.
• Mohato oa 2, mohato 6 (1) - Glyceraldehyde-3-phosphate le ho kena moea lona - mohato oo molek'hule e phosphorylated le oxidized ho 1,3-diphosphoglycerate.
• Mohato 7 (2) - lebisoa ho fetisetsa phosphate sehlopha ho ADP 1,3-diphosphoglycerate. Lihlahisoa ea ho qetela ea sethaleng sena ke sebopeho sa 3-phosphoglycerate le ATP.
• Mohato 8 (3) - phetoho ea ho tloha 3-phosphoglycerate 2-phosphoglycerate. Tšebetso ena e etsahala tlas'a tšusumetso ea potlakisang tsebetso ea lik'hemik'hale mutase. E le hore ba lik'hemik'hale itšoara joang ke ho ba teng ha magnesium (MG).
• Mohato 9 (4) - 2 fosfoglitserta dehydrated.
• Mohato 10 (5) - ka PEP le ADP isoa phosphates sephetho ho tswa temana ea mekhahlelo e fetileng. Matla a isoa fosfoenulpirovata le ADP. Ho itšoara joang ho hloka Ion potassium (K) le magnesium (MG).

liforomo Mutated tsa glycolysis

thulaganyou e glycolysis ka tsamaea le molokong o mong ka tlatsetso ea 1,3 le 2,3-bifosfoglitseratov. 2,3-phosphoglycerate susumetsoa sethothetsi tsa likokoana-hloko ke khona ho khutlela 'me rea sisinyeha glycolysis ka mokgwa wa 3-phosphoglycerate. Karolo e phethoang ke enzyme tsena ho fapane, mohlala, 2,3-bifosfoglitserat ho ba haemoglobin ho etsa hore oksijene ho feta ka dinama tse nyenyane tse ea, bebofatswe dissociation le fokotsa O ₂ amana le erythrocytes.

libaktheria tse ngata ho fetola sebopeho sa glycolysis ka mekhahlelo e sa tšoaneng, ho fokotsa palo ea bona kaofela, kapa tse fetolang ba le tlas'a tšusumetso ea enzyme tse sa tšoaneng. A karolo e itseng e nyenyane ea anaerobes na mekhoa e meng ea k'habohaedreite hlepha. thermophiles ba bangata ha ba le 2 feela potlakisang tsebetso ea lik'hemik'hale ea glycolysis, hore enolase le pyruvate kinase.

Glycogen le starch, disaccharides, le mefuta e meng ea monosaccharides

Aerobiki glycolysis - tshebetso bath le mefuta e meng ea k'habohaedreite, empa ka ho khetheha e le ntho ea tlhaho ho starch, glycogen, boholo disaccharides (Muñoz, galactose, fructose, sucrose, 'me batho ba bang). Mesebetsi ya mefuta eohle ea lik'habohaedreite tloaelo ikemiseditse ho generating matla, empa specifics e ka fapana morero oa eona, tšebeliso joalo joalo .. Mohlala, glycogen amenable glycogenesis hore ha e le hantle, ke fosfoliticheskim mekgwa ikemiseditse ho generating matla a ho petsoha glycogen. The glycogen tšoanang haholo ka ho bolokoa 'meleng ka bekapo mohloding matla. Kahoo, ho etsa mohlala, tsoekere, o ile a fumana ka nako ya lijo, empa ha metabolized ke boko, le bokeletseng sebete li tla sebelisoa ka khaello ea tsoekere 'meleng le ho sireletsa motho khahlanong le ho hlōleha ha hae ho tebile homeostasis.

Meaning of glycolysis

Glycolysis - e ikhethang, empa a se ke mofuta feela ea ho kena moea oa tsoekere 'meleng, li-cell ka prokaryotes le eukaryotes. enzyme Glycolytic ke metsi-qhibilihang ka har'a. Itšoara joang glycolysis tse ling lisele le lisele tse ka feela etsahala ka tsela ena, mohlala, ka boko le sebete lisele tse, nephron. mekhoa e meng ea ho kena moea oa tsoekere e sa sebelisoa ka ho makala ana. Leha ho le joalo, ha mesebetsi yohle o tšoanang oa ho glycolysis. Mohlala, mafura le dinama tse nyenyane tse sebete nakong tshilo ya dijo ntšang substrates hlokahalang bakeng sa tswakana ya tsoekere ho tloha mafura. dimela ba bangata ba sebelisa glycolysis ka tsela e eang karolo e khōlō ea tlhahiso ea matla.
