A biological catalyst increases the rate of biological processes/biological reactions.

A biological catalyst (enzymes) act to lower the activation energy of a chemical reaction.

Enzymes are bilogical catalysts that bind or separate substrates (chemicals the catalysts act on). the 'lock and key' model suggests that the enzyme doesn't change its form and only similarly shaped substrates can fit into the lock or cleft. it is similar to the toy children play with where you must fit the circular block into the circular hole and so on. The 'induced fit' model says thatthe enzyme molds itself around the substrate and separates or binds it from there. hope i helped!

What is a Catalyst mean in chemistry?

In Biology, a catalyst is a substance which speeds up a chemical reaction, without being changed themselves. Biological catalysts are found in living organisms.


What is a biological catalyst protein called?

A biological catalyst protein is called an enzyme. Enzymes speed up chemical reactions in living organisms by lowering the activation energy required for the reaction to occur.


Why do you need a catalyst during a enzyme reaction?

A catalyst speeds up the rate of a chemical reaction by lowering the activation energy needed for the reaction to occur. In the case of an enzyme-catalyzed reaction, the enzyme serves as a biological catalyst, allowing the reaction to occur more efficiently and at lower energy levels than it would without the enzyme.


What does a biological catalyst do?

Is catalyst a product of chemical reaction?

No a catalyst is unchanged by a chemical reaction, it does however serve to speed up the rate of the reaction.


Which component is affected when a catalyst is added to a chemical reaction?

The component affected when a catalyst is added to a chemical reaction is the reactants. The purpose of a catalyst is to speed up a reaction.
