Answer:
Option 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.
Explanation:
Breaking down of large molecules in to smaller molecules does not signify breaking down of energy stored in it and hence losing all the stored energy.  
Breaking down of large molecule is necessary to convert large molecules into small easily digestible molecules so that the food energy stored in them can be  stored  in some other form specifically chemical energy and can be used at later stages. However, in the process of conversion of large molecules into small molecules , a certain amount of heat energy is used.
Hence, option C is correct
