Each enzyme produced by the body is a protein, with the exception of a small group of catalytic RNA molecules called ribozymes.

Here's a breakdown:

* Proteins: Most enzymes are proteins, complex molecules made up of long chains of amino acids. These chains fold into specific three-dimensional shapes that create active sites, regions where the enzyme binds to and interacts with its substrate (the molecule it acts upon).

* Ribozymes: While most enzymes are proteins, a small number are made of RNA, a nucleic acid. These are called ribozymes. They are found in various cellular processes, like protein synthesis and RNA splicing.

Therefore, the most accurate answer is that each enzyme produced by the body is either a protein or a ribozyme.
