How much energy will the body assimilate per day with an efficiency of 50% if a person has consumed 450 g of carbohydrates?

1) Determine all the energy contained in 450 g of carbohydrates, if 1 g of them contains 17.6 kJ of energy: 17.6 x 450 = 7920 (kJ).
2) Since the efficiency of the process is 50%, it means that only 50% of the energy will be absorbed, i.e. 7920: 2 = 3960 (kJ).

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
