1. Malum harakat davomida muskul hujayralarida har daqiqada 20 kj energiya ajraladi

72/2 = 36 36(oqsil)

36+28 = 64(url,yog'
36-2 = 34(uglevod)
64-34 = 30(yog)
4280--------100
1284=x-------30
1284/38,9 = 33gr(yog')
II Usul
Oqsil(x) yog' van uglev(y)
x+y = 100
y-x = 28
x = 36
36-2 = 34(uglev)
36+34 = 70
100%-70% = 30(yog')
4280-------100%
1284=x-----30%
1284/38,9 = 33gr
