Biochemistry: Enzyme Index
A protein with catalytic properties due to its power of specific activation.
Chemical reactions need an initial
input of energy = THE ACTIVATION ENERGY.
One way to reach the transition state rapidly is to increase the temperature.
But biological systems are very sensitive to temperature changes.
Enzymes can increase the rate of reactions without increasing the temperature. They do this by lowering the activation energy. They create a new reaction pathway, "a short cut".
Enzyme controlled reactions proceed 108 to 1011 times faster than corresponding non-enzymic reactions.
The substrate of an enzyme are the reactants that are activated by the enzyme.
