Thaum lub sijhawm ua pa ntawm tes, carbon dioxide yog muab tawm raws li cov khoom pov tseg. Qhov no carbon dioxide tuaj yeem siv los ntawm photosynthesizing hlwb los tsim cov carbohydrates tshiab. Tsis tas li ntawd nyob rau hauv cov txheej txheem ntawm cellular respiration, oxygen gas yuav tsum tau ua raws li ib tug txais ntawm electrons.

Ib yam li ntawd, nws raug nug, dab tsi yog qhov xav tau rau kev ua pa ntawm tes?

Feem ntau ntawm cov kauj ruam ntawm kev ua pa ntawm tes muaj nyob rau hauv mitochondria. Oxygen thiab qabzib yog ob qho tib si reactants hauv cov txheej txheem ntawm kev ua pa ntawm tes. Cov khoom tseem ceeb ntawm kev ua pa ntawm tes yog ATP; cov khoom pov tseg muaj xws li carbon dioxide thiab dej.

Kuj Paub, cov pa oxygen siv li cas hauv cellular respiration? Cellular ua pa yog cov txheej txheem hlwb siv los ua kom muaj zog. Cov cell hauv peb lub cev ua ke cov piam thaj thiab oxygen los ua ATP thiab carbon dioxide. Oxygen ua ke nrog cov electrons thiab ob hydrogen ions ua dej. Thaum kawg, cov hydrogen ions ntws los ntawm ATP synthase los ua ATP.

Tom qab ntawd, ib tug kuj yuav nug, qhov twg peb tau txais roj rau cellular respiration?

Thaum lub sij hawm glycolysis, cov piam thaj molecule yog cleaved nyob rau hauv ob, tsim ob pyruvate molecules thiab lub zog molecule, ATP. Cov pyruvate molecules raug xa mus sai sai rau hauv mitochondria, qhov uas lawv tau siv nyob rau hauv seem ntawm cov ua pa txheej txheem. Cov piam thaj molecule yog thawj roj rau cellular ua pa.

Tus txheej txheem ntawm kev ua pa ntawm tes yog dab tsi?

Cellular ua pa yog cov txheej txheem ntawm kev rho tawm lub zog hauv daim ntawv ntawm ATP los ntawm cov piam thaj hauv cov zaub mov koj noj. Hauv theem ib, cov piam thaj tau tawg rau hauv cytoplasm ntawm cov cell hauv a txheej txheem hu ua glycolysis. Hauv theem ob, pyruvate molecules raug thauj mus rau hauv mitochondria.
