Enzymes are a type that reduces the activation engery of a chemical reaction?
catalysts
How does a enzyme increase the speed of a reaction?
The enzyme reduces the activation energy of the reaction, therefore chemical reaction speeds are increased.
When a catalyst is present and more or less activation energy is needed to start a chemical rection?
A catalyst reduces the amount of activation energy needed to start a chemical reaction.
How does the additions of a catalyst affect the energy of activation of a chemical reaction?
A catalyst changes the reaction mechanism to one with a lower activation energy; activation energy is lowered when a catalyst is added
Species is the reducing agent in a redox reaction?
The reactant that reduces another atom
What is the difference between positive catalyst and negative catalyst?
The substances which increase the rate of a chemical reaction are called a Positive Catalyst whereas The substances which decrease the rate of a chemical reaction are called Negative Catalyst. Positive Catalyst decreases the Activation energy of reactant molecules whereas negative catalyst increases the Activation energy of the reactant molecules. Positive Catalyst is also called the Promoter whereas negative catalyst is also called Inhibitor.
How does the interaction between an enzyme and its substrate change a chemical reaction?
Enzymes speed up the chemical reactions because when it forms a complex with its substrates, it reduces the activation energy that the reaction needs to proceed. Remember that the reaction itself is not altered, only the rate of reaction, and that the enzyme is not used or altered in the reactions.
Which species is the reducing agent in the redox reaction?
The reactant that reduces another atom.
What effect does an enzyme have on Ea?
Enzymes lower the activation energy (Ea) required for a chemical reaction to occur. By binding to reactant molecules and stabilizing the transition state, enzymes facilitate the formation of products from substrates. This acceleration of the reaction reduces the amount of energy needed to initiate the reaction, making it more favorable and allowing it to occur at a faster rate.
How does the catalyst and inhibitors affect the rate of chemical reaction?
Catalyst ensures that the activation energy of the molecules is lowered so there is effective collisions,and it does this in two ways;the transition and absorbtion states but inibitors even raises the activation energy and causes in effective collisions.
What does a catalyst do in a chemical reaction?
Reduces the activation energy of the reaction, which speeds up the progress of the reaction It increases the rate of a chemical reaction. However a true catalyst is not consumed in the reaction.
What species is the reducing agent in a redox reaction?
NADPH
