Which term describes energy in between the bonds of organic molecules?

• A. Mechanical energy
• B. Entropy
• C. Chemical energy
• D. Potential energy

Answer: (C)

The energy stored in the bonds of organic molecules is chemical energy. This energy arises from the specific arrangement of atoms and the bonds between them; it is a form of potential energy because it depends on how the atoms are bonded rather than on any motion. In chemical reactions, energy is released or absorbed as bonds break and new bonds form, which is why organisms harvest chemical energy from nutrients to power processes. Mechanical energy refers to motion and macroscopic positions, not the energy locked in molecular bonds. Entropy describes disorder, not energy content. While chemical energy is technically a type of potential energy, the scenario described—energy tied up in chemical bonds within organic molecules—is most precisely labeled chemical energy.
