Question

Energy is used to combine amino acid building blocks in order to build a large protein. What type of reaction is this?

Answer 1

We have to know the type of reaction involves in building a large protein from amino acid.

The reaction involves is condensation reaction.

Protein is made up of amino acids. Amino acid is the building block of proteins. Amino acids combine by condensation reaction and forms  polypeptide linkages (-CONH-) after loss of small molecules like water.
