* Enzymes: Enzymes are proteins. They are biological catalysts that speed up chemical reactions in the body.

* Antibodies: Antibodies are also proteins. They are part of the immune system and bind to specific antigens (foreign substances) to help neutralize them.

DNA and RNA are not enzymes or antibodies. They are nucleic acids that carry genetic information.

Here's a simple way to remember it:

* DNA & RNA: Information storage

* Proteins: Doing the work (including enzymes and antibodies)
