Enzymes are made up of

Explanation:
Enzymes are used as a biocatalyst and are proteins which inturn are the long chains of amino acids.
They contain multiple groups of α - amino acids which are bonded together by a peptide linkage.
Amino acids are joined to each other during the process of protein synthesis.
The enzymes are basically substances that help chemical reactions to occur quickly by catalyzing biochemical reactions.
Enzymes are made up of proteins with specific structure.

Final Answer:
Hence, the correct answer is option B: proteins with specific structure.
