They lower the activation energy needed to kick off the reaction and hence make the reaction proceed faster.

What are organic catalysts that increase the rates of chemical reactions within the cells?
Enzymes are general catalysts in the cell. They catalyse almost all reactions. They are proteins, some with other groups or ions attached.
Enzymes are examples of?
Enzymes are a special kind of bio molecules called proteins that catalyse rate of reactions.
What effects do catalysts have on an equilibrium system?
They catalyse both the forward and reverse reactions, so the position of equilibrium is unaffected. The system will however reach equilibrium more quickly.
What are the substances that increase the rate of a chemical reaction called?
A catalyst can speed up a chemical reaction. Another possible answer in the Biological sense is that Enzymes speed up chemical reactions, but these enzymes are catalysts of the chemical reactions.Different catalysts catalyse different reactions. For example iron is used as a catalyst in the Haber process (manufacture of ammonia).
How do you determine amount of enzyme consumed in a reaction?
There is no catalyst that is consumed in reaction which it is catalysing. In other reactions, eg. breakdown reactions, they do not catalyse their own breakdown! Enzymes are (bio)catalysts mainly as special protein molecules. In the reactions that ARE catalized they are not consumed, otherwise they were not 'catalists' but 'reactants'.
How do enzymes catalyse reactions?
Enzymes catalyse biochemical reaction by lowering the activation energy.
How do catalysts differ from inhibitors?
Inhibitors slow down chemical reactions. Catalysts speed up reactions.
Why are catalysts essential to biochemical reactions that occur in living organism What do you call these special biological catalysts?
Without catalysts many chemical reactions cannot occur; biological catalysts are called enzymes.
What do organisms contain to catalyse hydrolysis reactions in cells?
Enzymes.
Are enzymes used up in the reactions they catalyse?
The main function of enzymes in catabolic and anabolic reactions is to speed up the reactions and are therefore regarded as catalysts. Catabolic refers to break down of molecules while anabolic refers to build up of molecules.
All chemical breakdown processes in cells directly involved?
reactions that are controlled by catalysts
How do catalyst affect the energy reactions?
Catalysts doesn't affect the energy of reactions
