6. which process breaks energy-rich molecules down and releases energy-poor molecules?
which process uses energy-poor molecules to build an energy-rich one?

Hydrolysis process and ligation process

Explanation:

The process named hydrolysis helps in the breakdown of energy rich molecules to release energy poor moor molecules in presence of water

For example Adenosine tri phosphate (ATP) in presence of water undergo  hydrolysis to generate Adenosine di phosphate(ADP) and inorganic phosphate(Pi).

On the other hand ligation reaction helps in the synthesis of energy rich molecules by using energy poor molecules.

For example the reaction of ADP with inorganic phosphate(Pi) result in the formation of ATP a energy rich molecule.

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.

that is wrong, its not thymus.
