Are almost all enzymes proteins?

Yes, almost all enzymes are proteins. Enzymes are a type of protein that act as biological catalysts, speeding up chemical reactions in living organisms. There are also some RNA molecules called ribozymes that can act as enzymes.


Are almost all enzymes considered proteins?

Yes, almost all enzymes are considered proteins. Enzymes are biological molecules that act as catalysts to speed up chemical reactions within cells, and they are typically made up of proteins. However, there are some exceptions, such as ribozymes, which are RNA molecules that can also act as enzymes.
