You eat a bowl of beans as part of vour dinner. As vou 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.

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

its like this, "if i give a plant an unlimited amount of sunlight,then the plant will grow to its largest possible size."

hope it let me know if it does or doesn't =^-^=
