Question

Approximately ________ percent of all the energy released by nutrients is used by the body to carry on its normal functions, such as respiration, digestion, reproduction, muscular movement, circulation, and cellular regrowth.

Answer 1

Approximately 75% percent of all the energy released by nutrients is used by the body to carry on its normal functions, such as respiration, digestion, reproduction, muscular movement, circulation, and cellular regrowth. The rest will get stored up as energy. It is important to note that this percentage changes drastically between people. 

Answer 2

60-75%

The amount of energy used to carry on the normal functions (at rest) is called Basal Metabollic Rate.
