What is an agent that causes or speeds up a reaction without permanently altering itself?

Catalysts speed up chemical reactions without being used up or damaged in the process. Catalysts provide an active site that helps to bring chemicals together and thus increase the likelihood of a reaction taking place (and thus speeding up the reaction).
As well as speeding up reactions catalysts also reduce the activation energy needed for reactions to take place.
Enzymes are biological catalysts made out of protein.
All catalysts can be damaged or inhibited by either changing the shape of the active site or blocking it altogether.

Is saliva a catalyst?
No; a catalyst is used to speed up a reaction, and catalysts should remain in their initial states at the end of a reaction. Catalysts include: Fe Ni H2SO4 H3PO4 ** a system may act as a catalyst for altering water by definition the G7 water catalyst is such.
