Raws li qee qhov chaw tshiab tshaj qhov ATP Cov txiaj ntsig thaum lub sij hawm ua pa aerobic tsis yog 36-38, tab sis tsuas yog hais txog 30-32. ATP molecules / 1 molecule ntawm qabzib, vim: ATP : NADH +H+ thiab ATP : FADH2 ratios thaum lub sij hawm oxidative phosphorylation zoo li tsis 3 thiab 2, mas 2.5 thiab 1.5 feem.
Ntxiv mus, vim li cas 1 NADH ua 2.5 ATP?
Yuav kom dhau cov electrons los ntawm NADH mus kawg Oxygen txais, tag nrho ntawm 10 protons raug thauj los ntawm matrix mus rau inter mitochondrial membrane. Yog li ntawd rau NADH - 10/4= 2.5 TSI yog tsim los tiag. Ib yam li ntawd rau 1 FADH2, 6 protons yog tsiv li 6/4 = 1.5 ATP yog tsim.
Ib yam li ntawd, pes tsawg ATP sib npaug rau NADH? peb ATPs
Tsis tas li ntawd, vim li cas 1 NADH ua 3 ATP?
NADH tsim tawm 3 ATP Thaum lub sij hawm ETC (Electron Transport Chain) nrog oxidative phosphorylation vim NADH muab nws cov electron rau Complex I, uas yog nyob rau ntawm lub zog siab dua li lwm cov Complexes. Lub tshuab hluav taws xob rov qab mus rau Complex IV thiab rov tso cov hluav taws xob ntau dua hla cov membrane.
NADH ua ATP li cas?
Txhua NADH pumps peb protons whereas txhua FADH2 twj ob protons. Qhov kev tso tawm ntawm cov hluav taws xob thoob plaws hauv daim nyias nyias ua rau muaj qhov sib txawv ntawm Hydrogen atoms thoob plaws hauv daim nyias nyias. Qhov no yog vim li cas txhua tus NADH ua peb ATP thiab txhua FADH2 ua 2 ATP . Electron thauj system hauv mitochondria ua ATP.

Puas yog Phosphorus yog hlau lossis tsis yog hlau?
Phosphorus yog cov hlau tsis muaj hlau uas nyob hauv qab nitrogen hauv pawg 15 ntawm lub sijhawm. Cov khoom no muaj nyob rau hauv ntau hom, uas yog dawb thiab liab yog qhov zoo tshaj plaws paub. Dawb phosphorus yog twv yuav raug hu ntau exciting ntawm ob
Puas yog beryllium yog hlau lossis nonmetal lossis metalloid?
Beryllium yog hlau. Nws yog nyob rau hauv alkaline ntiaj teb hlau pawg nyob rau hauv lub periodic lub rooj thiab muaj tshuaj thiab lub cev muaj zog zoo ib yam li cov magnesium thiab txhuas, tab sis muaj ib tug ntau dua melting point tshaj ob qho tib si
Puas yog carbon hlau lossis nonmetal lossis metalloid?
Carbon muaj 4 electrons nyob rau hauv nws lub valence plhaub uas ua rau nws ib tug metalloid tab sis feem ntau nws yog suav hais tias yog tsis yog hlau
Puas yog malleable hlau lossis nonmetal lossis metalloid?
Hlau, Metalloids, thiab Nonmetals. Cov ntsiab lus tuaj yeem faib ua hlau, nonmetals, lossis metalloids. Cov hlau yog cov khoom siv hluav taws xob zoo ntawm cov cua sov thiab hluav taws xob, thiab tuaj yeem ua tau zoo (lawv tuaj yeem muab hammered rau hauv cov ntawv) thiab ductile (lawv tuaj yeem kos rau hauv cov hlau). Cov metalloids yog nruab nrab hauv lawv cov khoom
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
