Maloetse a mitochondrial: ke eng, lisosa, matšoao le kalafo - Bophelo

Litaba

Maloetse a Mitochondrial ke mafu a lefutso le a lefutso a khetholloang ke khaello kapa ts'ebetso e fokotsehileng ea mitochondria, e nang le tlhahiso e sa lekanang ea matla ka seleng, e ka lebisang lefung la sele mme ha nako e ntse e ea, setho se hloleha.

Mitochondria ke meaho e menyenyane e teng ka har'a lisele tse ikarabellang ho hlahisa matla a fetang 90% a hlokahalang bakeng sa lisele ho etsa mosebetsi oa tsona. Ntle le moo, mitochondria le eona e kenya letsoho molemong oa ho theha sehlopha sa heme sa hemoglobins, metabolism ea cholesterol, li-neurotransmitters le tlhahiso ea li-radicals tsa mahala. Kahoo, phetoho efe kapa efe ts'ebetsong ea mitochondria e ka ba le litlamorao tse mpe bophelong.

Matšoao a mantlha

Matšoao a mafu a mitochondrial a fapana ho latela phetoho, palo ea mitochondria e amehileng ka har'a sele le palo ea lisele tse amehang. Ntle le moo, li ka fapana ho latela hore na lisele le mitochondria li hokae.


Ka kakaretso, matšoao a ka supang mafu a mitochondrial ke ana:

  • Bofokoli ba mesifa le tahlehelo ea tšebelisano ea mesifa, kaha mesifa e hloka matla a mangata;
  • Liphetoho tsa kelello le ho senyeha ha boko;
  • Liphetoho tsa mala, ha ho na le liphetoho tse amanang le ts'ebetso ea tšilo ea lijo;
  • Mathata a pelo, ophthalmic, liphio kapa sebete.

Maloetse a mitochondrial a ka hlaha nako efe kapa efe bophelong, leha ho le joalo phetoho ea phetoho e bonahala kapele, matšoao a ba matla le ho feta le ho bolaea.

Mokhoa oa ho hlahloba o etsoa joang

Ho fumanoa ho le thata, hobane matšoao a lefu lena a ka supa maemo a mang. Tlhahlobo ea mitochondrial hangata e etsoa feela ha sephetho sa litlhahlobo tse atisang ho botsoa se sa tsejoe.

Ho khetholla lefu la mitochondrial hangata ho etsoa ke lingaka tse ikhethileng ka mafu a mitochondrial ka liteko tsa liphatsa tsa lefutso le limolek'hule.


Lisosa tse ka bang teng

Maloetse a mitochondrial ke a liphatsa tsa lefutso, ke hore, a bonahala ho latela boteng kapa ho ba sieo ha liphetoho liphatseng tsa lefutso ka har'a DNA ea mitochondrial le ho latela tšusumetso ea phetoho e kahare ho sele. Sele ka 'ngoe' meleng e na le mitochondria e makholo cytoplasm ea eona, e 'ngoe le e' ngoe e na le liphatsa tsa lefutso.

Mitochondria e ka har'a sele e le 'ngoe e ka fapana, joalo ka ha bongata le mofuta oa DNA ka mitochondria li ka fapana ho tloha seleng ho isa sele. Lefu la mitochondrial le etsahala ha kahare ho sele e le 'ngoe ho na le mitochondria eo liphatsa tsa eona tsa lefutso li fetohileng' me sena se na le tšusumetso e mpe ts'ebetsong ea mitochondria. Kahoo, mitochondria e nang le bofokoli bo eketsehileng, matla a fokolang a hlahisoa mme monyetla o moholo oa lefu la sele o beha tšebetsong tšebetso ea setho seo sele e leng sa sona.

Kalafo e etsoa joang

Kalafo ea lefu la mitochondrial e ikemiselitse ho khothaletsa boiketlo ba motho le ho liehisa tsoelo-pele ea lefu lena, mme ts'ebeliso ea livithamini, hydration le phepo e nepahetseng e ka buelloa ke ngaka. Ntle le moo, e eletsoa khahlano le tloaelo ea ho ikoetlisa ka matla haholo hore ho se ke ha haelloa ke matla ho boloka mesebetsi ea bohlokoa ea 'mele. Kahoo, ho bohlokoa hore motho a baballe matla a bona.


Le ha ho se na kalafo e ikhethileng ea mafu a mitochondrial, ho a khonahala ho thibela phetoho e tsoelang pele ea DNA ea mitochondrial hore e se ke ea fetisoa ho tloha molokong o mong ho ea ho o mong. Sena se tla etsahala ka ho kopanya khubu ea sele ea lehe, e lumellanang le lehe le emolisitsoeng le peo, le mitochondria e phetseng hantle e tsoang ho mosali e mong, ea bitsoang mofani oa mitochondria.

Kahoo, lesea le ka pōpelong le ne le tla ba le liphatsa tsa lefutso tsa batsoali le mitochondrial ea motho e mong, eo ka tloaelo e bitsoang "lesea la batsoali ba bararo". Leha e sebetsa hantle mabapi le tšitiso ea lefutso, mokhoa ona o ntse o hloka ho etsoa khafetsa le ho amoheloa ke likomiti tsa melao ea boitšoaro.
