If you were still interested, basically condensation reactions are anabolic and hence are endergonic. Synthesising a large molecule from smaller ones means you are creating new chemical bonds which requires a net input of energy.
Hydrolysis reactions are catabolic and hence exergonic. Hydrolysing a large molecule into smaller ones means you are breaking it down, and thus releasing a net amount of energy which was stored in chemical bonds.
I must add, condensation reactions aren't always endergonic. If you think of acid-base reactions as condensation reactions, they surely aren't endergonic. Synthesising a large molecule from smaller ones does, in general, require energy, but not because you're creating new chemical bonds. That in itself isn't why larger molecules require energy. Larger molecules require energy to make because molecules have an inherent tendency to want to be small. If you hydrolyse ATP, for instance, sure you're breaking a P-O-P bond, but you're actually forming a new O-P bond as well. Breaking chemical bonds always requires energy. Even F2, a molecule with a really weak bond, requires energy to break it. If chemical bonds released energy when broken...why would they form?
Just something I thought the chemistry students amongst you guys might appreciate
