They lower the activation energy of catalytic reactions. I think I remember a few ways they do this. One: they can provide a safe haven for two substrates to interact. Two: They can actually stress the bonds of a substrate causing the reaction by new bonds forming. Three: These enzyme proteins, like all proteins. are amino acids with R groups. Some enzymes can catalyze a reaction with the R group.
Usually platinum, rhodium and/or palladium.
The platinum catalyst in a car's catalytic converter works through adsorption to change toxic carbon monoxide into less-toxic carbon dioxide.
A catalyst that involves an intermediate compound is chlorine. In the ozone layer of our Earth's atmosphere there are many ozone molecules, composed of three atoms of oxygen. If a chlorine atom is present, it will act as an intermediate compound and steal one oxygen atom from ozone, leaving stable oxygen. The chlorine-oxygen compound formed is unstable, and will break down to release its oxygen, letting the chlorine atom repeat the process about a million times a second.

That catalyst is known as chlorophyl.

Anything that acts that way is a catalyst. It is the definition.

Enzyme
Enzymes are the organic molecules that act as biological catalysts.
Molecules that act as catalysts in biological systems are enzymes. Enzyme catalyze chemical reactions by lowering the activation energy.

Oxygen acts as a reactant.
That catalyst is known as chlorophyl.

Salt acts as a catalyst. Acid tends to be a reactant.
