Title: Is some of the energy of food lost during digestion by enzymes due to the breakdown of bonds? Post by: mai2000 on Feb 17, 2017 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 :) Title: Re: Is some of the energy of food lost during digestion by enzymes due to the breakdown of bonds?

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