Biologik masalalar

Uglevod- 450 g x 4.1=7920 kJ
4) 1760+3890+7920=13570 kJ jami ovqatdan ajralgan energiya
5) 180 g glyukoza parchalansa-----------2800 kJ energiya
872,4 g glyukoza--------------------x=13570
6) 3890 kJ : 7920 kJ x 100 %=49 %
Demak javob: C


8.Masala. Azimboy aka bir kecha kunduzda 150 g oq non, 2 ta tuxum, 200 g mol go’shti, 105 g pishloq, va 200 g shaker iste’mol qildi. Bu ovqatdan ajralgan energiyani barchasi asosiy moddalar almashinuvini ta’minlash uchun sarflangan bo’lsa, bunday ovqatlanishdan so’ng Azimboy aka uzoq vaqt ovqatlanmasa, tana massasi necha kg kamayganda halok bo’ladi?
A) 50,25 kg B) 34,9 kg C) 29,43 kg D) 12 kg


Ishlanishi:


1) Bu masalani ham ishlash uchun jadvaldagi ozuqalardan ajralayotgan energiyani bilish zarur:
2) 100 g oq nonda-------6,7 g oqsil------0,7 g yog’-----50,3 g uglevod mavjud
150 g da------------x=10,05 g---------x=1,05 g---------x=75,45 g
3) 10,05 x 4,1=41,205 kkal; 1,05 g x 9,3=9,765 kkal, 75,45g x 4,1=309,45 kkal
4) 41,205+9,765+309,45=360,315 kkal oq nondan ajralagan umumiy energiya


5) 1 tuxumdan-------12,5 g oqsil---------12,1 g yog’------0,55 g uglevod
2 tuxumdan--------x=25 g------------x=24,2-----------1,1 g
6) 25 x 4,1=102,5 g oqsil, 24,2 x 9,3 =225,06 yog’, 1,1 g x 4,1=4,51 g uglevod
7) 102,5+225,06+4,51=332,07 kkal 2 ta tuxumdan ajralgan energiya


8) 100 g mol go’shtida---------29,2 g oqsil-------7 g yog’
200 g go’shtda------------x=58,4 g--------------x=14 g
9) 58,4 x 4,1=237,8 kkal, 14 x 9,3=130,2 kkal
10) 130,2+ 237,8=368 kkal 200 g mol go’shtidan ajralgan energiya


11) 100 g pishloqda-------22,6 g oqsil-------25,7 g yog’
105 g pishloqda--------x=23,73 g------x=26,985 g
