A catalyst is a substance that speeds up the rate of a chemical reaction. Catalysts work by lowering a reaction's activation energy.

A substrate is a reactant of an enzyme-catalyzed reaction.

A catalyst is a substance that speeds up the rate of a chemical reaction without being consumed in the process. It does this by providing an alternative pathway with a lower activation energy for the reaction to occur. The substrate is the molecule that interacts with the catalyst to undergo a chemical reaction, leading to the formation of products.

What is the substance that a catalyst works on?

The substrate on which a catalyst works is called its substrate


Are substrate and catalyse the same thing?

No, substrate and catalyst are not the same thing. A substrate is the molecule that is acted upon by an enzyme, while a catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process. Enzymes act as catalysts in biological reactions by facilitating the conversion of substrates into products.


What is a reactant that binds to a catalyst?

A reactant that binds to a catalyst is known as a substrate. Substrates bind to the active site of the catalyst, where the chemical reaction takes place. This binding lowers the activation energy required for the reaction to occur.


What do you call a substance that accelerates the rate of a chemica reaction?

A substance that accelerates the rate of a chemical reaction is called a catalyst.


What is the difference between a reactant and a catalyst?

A reactant is a substance that participates in a chemical reaction and undergoes a change. A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process. Reactants are consumed in a reaction, while catalysts remain unchanged at the end of the reaction.


Is sugar a good catalyst?

Sugar is not a catalyst because it does not participate in the chemical reaction by lowering the activation energy or being consumed in the reaction. It is often used as a reactant or substrate in various biochemical processes instead of a catalyst.


Why a catalyst is not involved chemically in chemical reaction?

The catalyst is not a reactant; a catalyst only favors a chemical reaction, the reaction rate and yield.


Are substrate and reactant the same or different?

Substrate and reactant are different. A substrate is a specific molecule or compound that undergoes a chemical reaction catalyzed by an enzyme. A reactant is a general term for any substance that is consumed or transformed in a chemical reaction. Substrates are a subset of reactants.


What is an enzyme complex substrate?

An enzyme-substrate complex uses the reactants(substrates) and the enzyme. The enzyme is like a catalyst that reduces the required activation energy and speeds up the chemical reaction.


What term describe a substance that lowers the amount of energy needed to start a chemical reaction?

Catalyst


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.


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.
