A catalyst works by providing a reaction route with a lower activation energy. An inhibitor slows a reaction and can work in several ways, for instance by tying up one of the reactants. We also use the term when we say catalyst inhibitor, which is something which binds to the active sites on a heterogeneous catalyst.

What are catalysts that slow down a reaction?
The catalysts can be used to increase or decrease the speed of a chemical reaction. The catalysts which reduce the speed of a reaction are called negative catalysts. They decrease the speed of the reaction by increasing the activation energy of the reaction.
What is a substance that lowers the activation energy for a chemical reaction but is not changed or used up in the reaction?
This is called a catalyst. In biology, it is referred to as an enzyme (biological catalyst). Catalysts can also be used to speed up or slow down chemical reactions.
What role do catalysts play in chemical reactions?
A catalyst is a chemical species that alters the rate of a chemical reaction without undergoing any type of change. Such catalysts that slow down a reaction are called negative catalysts or poison.
What is the name of substance that slows reaction?
The substance that slows down a chemical reaction is an inhibitor. Instead you could also call an inhibitor an anticatalyst.-anticatalyst `antee'katlist1. (chemistry) a substance that retards a chemical reaction or diminishes the activity of a catalyst
What does biological catalyst mean?
Enzymes are biological catalysts. This means they speed up a chemical reaction, but are not broken down or changed by it. They lower the amount of energy required for a chemical reaction to tack place.

How do catalysts differ from inhibitors?
Inhibitors slow down chemical reactions. Catalysts speed up reactions.

What type of substance slows down chemical reaction?
Chemical reactions can be either sped up or slowed down by catalysts.
What roles do enzyme play in digestion?
Enzymes are proteins that act as biological catalysts. Catalysts are substances that accelerate a chemical reaction. They decrease the activation energy of a chemical reaction.
Does the addition of a catalyst to a chemical reaction increase the reaction rate?
Most catalysts do, but not all. Some catalyst can also slow down the speed, so they are generally referred to as Negative catalyst
What does a enzyme do in chemical reaction?
An enzyme generally lowers the activation energy necessary for a reaction to proceed. This in turn may cause more of the reactants to go to products.
What is the name of substance that slows reaction?
The substance that slows down a chemical reaction is an inhibitor. Instead you could also call an inhibitor an anticatalyst.-anticatalyst `antee'katlist1. (chemistry) a substance that retards a chemical reaction or diminishes the activity of a catalyst
What do catalysts do to the activation energy of a chemical reaction?
A chemical catalyst is a substance that lowers the required activation energy of a reaction. The activation energy is the amount of energy required to "activate" or start a process, this can be in the form of many things, such as heat. A chemical catalyst can be seen as a kind of shortcut in a chemical process to speed things up. A catalyst can also be used to increase the activation energy, so that the reaction will slow down. This is useful for slowing down reactions that are normally too fast to witness.
What does biological catalyst mean?
Enzymes are biological catalysts. This means they speed up a chemical reaction, but are not broken down or changed by it. They lower the amount of energy required for a chemical reaction to tack place.
What is the the purpose of catalysts and inhibitors in a reation?
A catalyst is a substance that can speed up a reaction without being involved in the reaction. A catalyst is therefore often used to speed up a reaction. These are often used in the production of chemicals since very few are needed for a long time to keep a reaction going fast (they do not change during the reaction, and therefore can be reused). An inhibitor does the opposite - it slows down the reaction and is not involved in the reaction. These are often used in foods and anti rust products to slow foods from rotting and the process of oxidation (rusting), respectively.
