Enzymes act as a catalyst or substance that lowers the energy process in a chemical reaction.
A catalyst is a substance that lowers the activation energy needed to start a chemical reaction.
A catalyst, such as an enzyme, lowers the activation energy of a reaction. A substrate is a substance in the reaction that is being catalyzed.
A catalyst.
It lowers the activation energy for a chemical reaction. So, you do not need so much energy to get a chemical reaction started.
An enzyme lowers the activation energy of a reaction. This lowers the minimum energy required for the reaction to occur. So, the reaction gets significantly faster.
