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.

In over simplistic terms, cellular metabolism (reactions in the cell ie. photosynthesis in plants) need to occur quickly, or the organism wouldn't survive.

A catalyst is a substance that facilitates chemical reactions without itself changing. Enzymes act as catalysts in the processes of food digestion and DNA synthesis.

Enzymes are protein catalysts and therefore are biological molecules that perform enzymatic reactions.
