Here's a breakdown:
* Activation energy: This is the minimum amount of energy required for a chemical reaction to occur.
* Enzymes: These are biological catalysts that speed up reactions without being consumed in the process.
* How they work: Enzymes provide an alternative reaction pathway with a lower activation energy. They do this by:
* Binding to the reactants (substrates): This brings the substrates together in the correct orientation for the reaction to occur.
* Stabilizing the transition state: This is the unstable intermediate form of the reactants during the reaction. By stabilizing it, the enzyme reduces the energy required to reach it.
By lowering the activation energy, enzymes make it easier for reactions to occur, allowing them to proceed at faster rates under normal conditions.
