Enzymes act as catalysts. They speed up the reaction time.
A catalysts speeds up the reaction in living things.

Enzymes are needed to lower the activation energy so that the reaction can occur at temperatures at which living things can survive.

A catalyst. Definition from Pretence Hall Biology: A catalyst is a protein that speeds up the rate of a chemical reaction.
The function of enzymes in living things is to catalyze (instigate, speed up) chemical reactions.
Enzymes lower the activation energy (or free energy of activation for the very scientific) of the chemical reactions they catalyse. The enzymes can make a reaction proceed much more quickly than it otherwise would by astronomical figures, e.g. 109 times! Enzymes don't affect the equilibrium position, but they do affect the rate.

it speed up or slow down reaction in a substrate and aids blood clotting,digestion of food. And others....
Enzymes are proteins found in living things that act to catalyze specific reactions. Made up of a complex of amino acids, enzymes are part of every chemical reaction in living things. They aid in digestion, the growth and building of cells, and all reactions involving the transformation of energy. Inside the cell, enzymes create RNA and DNA by facilitating the reaction of ribose with adenosine. They also specify the sites for linking to build RNA along a DNA template.
