Enzymes
Enzymes are biological catalysts. This means that enzymes accelerate a wide variety
of very particular chemical reactions within living organisms. They represent a major
aspect of cellular regulation and function. Almost all metabolic processes including
transportation of information and processes within the cytoskeleton of the cell need
enzymes in order to maintain function and sustain the life of the organism.
Chemically, enzymes are like any catalyst and are not consumed in chemical
reactions, nor do they alter a reaction other than through acceleration. Enzymes differ
from most other catalysts by being much more specific in their function and reaction.
The molecules upon which enzymes may act are called substrates and the enzyme
helps convert the substrates into different molecules known as products. Enzyme
activity can be affected by other molecules: inhibitors are molecules that decrease
enzyme activity, and activators are molecules that increase activity.
