. A non proteinaceous enzyme is

A: Ligase

B: Deoxyribonuclease

C: Lysozyme

D: Ribozyme


Best Answer


  • Enzymes are molecules that promote reactions in a living cell without undergoing significant change, i.e. they are biological catalysts that are similar to proteins. 

However, some chemicals work in a similar fashion to protein enzymes in catalyzing chemical reactions. They are called non-proteinaceous enzymes.

  • Ribozymes are RNA enzymes, chemically made up of RNA’s while lysozymes, ligase and deoxyribonuclease all are proteinaceous enzymes. 

Final answer:

Correct Answer is D:Ribozymes
