Question

The building of large molecules by the enzymatic removal of water is an example of what kind of reaction?

Answer 1

the removal of water caused by the formation of a large molecule (like a polymer) are usually called condensation mechanisms, since you can often see droplets of water "condensing" out of the reaction mixture.

Answer 2

Hydrolysis reaction

Answer 3

It is indeed a condensation reaction. A hydrolysis reaction is the reverse -- adding water to break apart large polymers.
