A type of enzyme catalyzed chemical reaction that is very common in biology and involves joining building blocks monomers together to build a larger molecule known as Polymer

condensation or dehydration synthesis

Explanation:

A condensation reaction can be described as a reaction in which two molecules combine to form a larger molecule. A water molecule is usually dispersed during this reaction.

For example, two amino acids join to form a protein. The bond formed between them is known as dipeptide bond.

Dehydration synthesis is also a reaction in which molecules via covalent bonds to form larger molecules. As water molecule is released during this process, this reaction is termed as dehydration synthesis.
