knowing that chemical energy of food is converted to heat energy to be used by the body in many anabolic reactions- it is the breaking down of bonds that releases energy.
Does that mean that some of the energy of food is lost during digestion as enzymes breakdown large food molecules into smaller soluble ones? or is it the common concept of loosing energy during digestion because not all the food is absorbed and some are egested ?
Thanks in advance Slight Smile

That's correct, the calories contained in the food are not entirely converted into usable energy.
