Mitochondria - Tig lub Powerhouse
Mitochondria yog lub npe hu ua powerhouses lub cell . Lawv yog cov organelles uas ua zoo li lub plab zom mov uas siv cov as-ham, zom lawv, thiab tsim lub zog nplua nuj molecules rau lub cell . Cov txheej txheem biochemical ntawm lub cell yog lub npe hu ua cellular ua pa
Ntawm no, tus qauv ntawm mitochondria tso cai rau lub cev ua pa li cas?
Cov aerobic theem ntawm cellular ua pa nyob rau hauv eukaryotes tshwm sim nyob rau hauv organelles hu ua mitochondria . Mitochondria , organelles tshwj xeeb los nqa tawm aerobic ua pa , muaj ib daim nyias nyias folded rau hauv cristae, uas ua rau ob qho tib si compartments: lub puab membrane qhov chaw thiab lub matrix.
Tsis tas li ntawd, cov qauv ntawm mitochondria ua li cas rau oxidative phosphorylation? Cov enzymes uas pab catalyze oxidative phosphorylation yog embedded nyob rau hauv lub puab mitochondrial daim nyias nyias. Cov xwm txheej ntawm lub voj voog citric acid thiab oxidative phosphorylation coj qhov chaw hauv matrix. Sab nrauv membrane ntawm lub mitochondria Nws yog permeable loj heev thiab tso cai rau ntau lub molecules kom dawb do diffuse hla nws.
Ib yam li ntawd, cov qauv ntawm mitochondria cuam tshuam li cas rau nws txoj haujlwm?
Qauv ntawm Mitochondria Lub txheej membrane npog qhov chaw ntawm lub mitochondrion , thaum lub puab membrane nyob rau hauv thiab muaj ntau folds hu ua cristae. Cov folds nce thaj tsam ntawm daim nyias nyias, uas yog ib qho tseem ceeb vim hais tias lub puab membrane tuav cov proteins koom nrog hauv cov saw hlau thauj electron.
Lub luag haujlwm ntawm mitochondria yog dab tsi?
ua pa
Pom zoo:
Dab tsi yog qhov txiaj ntsig tseem ceeb ntawm kev taw qhia ntawm tes los ntawm kev sib cuag lub cev ncaj qha?
Kev taw qhia kuj tshwm sim ntawm cov hlwb uas yog kev sib cuag ntawm lub cev. Kev sib cuam tshuam ntawm cov proteins ntawm qhov chaw ntawm cov hlwb tuaj yeem ua rau muaj kev hloov pauv hauv cov cwj pwm ntawm tes. Piv txwv li, cov proteins nyob rau saum npoo ntawm T-cells thiab antigen nthuav tawm cov hlwb sib cuam tshuam los ua kom muaj kev taw qhia hauv T-cells
Vim li cas cov nuj nqis tseem ceeb tseem ceeb thaum qhia txog kev ntsuas?
Cov duab tseem ceeb yog qhov tseem ceeb los qhia qhov tseeb ntawm koj cov lus teb. Qhov no yog qhov tseem ceeb hauv kev tshawb fawb thiab engineering vim tias tsis muaj cov cuab yeej ntsuas tuaj yeem ua qhov ntsuas nrog 100% precision. Siv cov nuj nqis tseem ceeb tso cai rau tus kws tshawb fawb paub tias cov lus teb meej npaum li cas, lossis qhov tsis paub meej npaum li cas
Yuav ua li cas yog vim li cas tus qauv ntawm ib qho enzyme tseem ceeb heev rau nws txoj haujlwm hauv cov khoom muaj sia?
Enzymes ua kom cov tshuaj tiv thaiv uas tshwm sim hauv cov hlwb. Qhov kev ua haujlwm no cuam tshuam ncaj qha rau lawv cov qauv, nrog rau txhua qhov enzyme tau tshwj xeeb zoo li tus ua kom muaj zog rau ib qho tshuaj tiv thaiv. Kev poob ntawm cov qauv ua rau poob haujlwm. - Kub, pH, thiab kev tswj cov molecules tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cov enzymes
Tus qauv qauv yog dab tsi Qhov txawv ntawm tus qauv qauv thiab tus qauv molecular yog dab tsi?
Cov mis mos molecular siv cov cim tshuaj thiab cov ntawv sau npe los qhia cov naj npawb ntawm cov atoms sib txawv hauv cov molecule lossis compound. Ib qho empirical formula muab qhov yooj yim tshaj plaws, tag nrho tus lej piv ntawm atoms hauv ib qho chaw. Cov qauv qauv qhia txog kev sib koom ua ke ntawm cov atoms hauv cov molecule
ATP yog dab tsi thiab vim li cas nws tseem ceeb rau kev ua pa ntawm tes?
ATP muaj ib pawg phosphate, ribose thiab adenine. Nws lub luag haujlwm hauv kev ua pa ntawm tes yog qhov tseem ceeb vim nws yog lub zog txiaj ntawm lub neej. Lub synthesis ntawm ATP absorbs zog vim ntau ATP yog tsim tom qab
