You eat a bowl of beans as part of your dinner. As you digest the beans, the proteins that are present get broken down to their component amino acids. As your body destroys the macromolecules that were present in the beans, is the energy present in those molecules destroyed?
A. Yes. By breaking down these macromolecules, some of the energy they contained is destroyed. B. No. While the vast majority of the energy contained in these macromolecules is converted to heat, it is not actually destroyed. C. No. The energy contained within these macromolecules is converted into other forms of chemical energy and kinetic energy, though some is lost as heat. D. No. Breaking down molecules does not lead to the release of energy.
