INTRODUCTION:
The cellular activity of all organisms is controlled through the use of enzymes. An enzyme is a special type of biological molecule, usually a protein, which speeds up a chemical reaction; most are soluble in water or a dilute salt solution. There are about 4000 different enzymes in a typical living cell. If even one of these enzymes is missing or defective, the results can disastrous. Enzymes have a unique three dimensional shape, and this shape determines which reaction it catalyzes. Another term that is used to describe an enzyme is catalyst. A catalyst is a substance that speeds up a reaction, …show more content…
