1) 38x + 2y = 126
x + y = 9
x = 3
y = 6
Bir mol glukoza
hosil qilish uchun
o'simlik 720 kj (18 ATF•40 kj)
energiya
sarflaydi
1 mol ------ 720 kj
3 mol ------ x = 2160 kj
Javob: D)
2160
42.Disimilatsiya jarayonida glyukozani parchalanishidan muskul hujayralarida 8800
kj energiya va 118 ta ATF hosil boʼldi, glyukozning necha % toʼliq parchalangan
A) 40% B) 95% C) 60% D) 5 %
Yechimi
1) 2800x+200y=8800
38x+2y=118
x=3 toʻliq
y=2 chala
2) 2+3=5
3) 3:5=0,6 • 100=60 %
Javob: C)
60 %
43. 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 bòlgan 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.
