The active come in is made up of a unique sequence of R groups, with different shapes, giving the site its shape. There, the subst assess binds and undergoes a successive of catalytic reactions after which the products leave the active site. This leaves the enzyme free to hold back out more catalytic reactions. An enzyme is also sensitive to lurchs in temperature and pH. Different enzymes have a different optimum temperature and pH at which to function. Most enzymes are denatured at aristocratic temperatures, and deactivated at low temperatures.

The enzyme consistence unchanged after the reaction, and merely serves to speed up the rate of reaction. In other cases, the mere presence of the enzyme is a harbinger to a whole cycle...
