Typically glycolysis. Glycolysis is a process by which sugars (specifically glucose) is broken down into ATP (energy). There are, however, many pathways to derive energy from differently moleculs (including lipids and carbohydrates).

Nucleic acids (DNA and RNA)

One is polar and one is nonpolar.

Hydrolysis uses water in the reaction and dehydration removes it. The answer is dehydration.
