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

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.

Amino acid contains an amine group (-NH₂) and one carboxylic acid (-COOH) group. When one amino acid reacts with other amino acid, they lose water molecule and form amide through peptide linkage formation.

If two amino acids combine, then monopeptide is formed while three amino acids form two peptides.

the answer is a and have a great day

your answer would be “dry”
