Sitoplazmada 120 mol ADF
120•0,25 = 30
C6H12O6+2ADF=2C3H6O3
2 ADF ------- 2 mol sut k-ta
30 ------- x = 30 mol
Anaerob : aerob
1 : 12 ADF
30 : 360 ADF
2C3H6O3+36ADF=36 ATF
36 ADF ------- 36 ATF
360 ADF ------- 360 ATF
2 mol sut k-ta --------- 36 ATF
20 = x ---------------- 360 ATF
30 - 20 = 10 mol parchalanmagan
2C3H6O3+36ADF=36 ATF
2 mol --------- 36 ATF
10 mol ------- 180 ATF
360 ------ 100 %
180 ------ x = 50 %
360 + 180 = 540 ATF

Glukoza molekulasining chala parchalangan qismi to‗la parchalangan qismidan 3 birlikka
ortiq. To‗liq parchalangan qismidan hosil bo‗lgan ATF soni chala parchalangan qismidan
xosil bo‗lgan ATF sonidan 7,6 marta ko‗p. Jami parchalangan glukoza molekulalar sonini
(a) va to‗liq parchalanishida hosil bo‗lgan energiya miqdorini (kJ) (b) aniqlang.

Parchalangan C6H12O6 ni X bilan belgilaymiz
x mol 38x
C6H12O6 --> 38 ATF
x+3 mol 2x+6
C6H12O6 --> 2C3H6O3 + 2 ATF
Shunga asoslangan holada tenglama

Agar maxsar organizmida glukoza kunduz kuni 2 soat davomida faqat tòliq usulda
parchalansa, shu vaqt ichida sitoplazmada hosil bòlgan ATF 18 molni tashkil qilsa, u holda
shu vaqt davomida xloroplastlarda hosil boʻlgan ATF ni molini aniqlang?
A) 540
B) 9720
C) 324
D) 30
#YECHIMI
1) Glukoza sitoplazmada tòliqsiz usulda parchalanadi.
1 ------- 2 ATF
x ------- 18
x=9
2) Tôliq parchalanish mitoxondriyada ketadi.
1 -------- 36
9 -------- x= 324 ATF
3) Xloroplastlarda mitoxondriyaga nisbatan 30 marta kòp ATF sintezlanadi.
324·30=9720

180 g glukoza hosil qilish uchun 18 mol ATF sarflanadi.
1) 180 ------ 18 ATF
2700 ---- x = 270 ATF
2) 270 • 3 = 810 ATF
