Enzymes are globular proteins
which act as biological catalysts. They are able to temporarily
bind with substrate molecules due to an region know as the active site. Because enzymes are proteins their
activity can be affected by pH and temperature. The catalytic ability of enzymes depends on their
three dimensional shape, this is more commonly refered to as
the enzymes tertiary structure. During an enzyme catalysed
reaction a transition occurs during which the reactants are referred
to as the enzyme
substrate complex. |
