What is the Overall Percent of Nutrient Derived Energy That

Question

What is the overall percent of nutrient derived energy that is lost as heat?​
A)​35%
B)50%
C)60%
D)75%
E)​90%

Accepted Answer

According to the second law of thermodynamics, there is always some energy lost as heat in any energy transfer or transformation. The overall percent of nutrient derived energy that is lost as heat varies depending on the organism and the specific metabolic processes, but typically it is around 75%. This means that only about 25% of the energy consumed is actually used for growth, maintenance, or other biological processes.
