Here's a breakdown:
* Catalysts are substances that speed up chemical reactions without being consumed in the process. They do this by providing an alternative reaction pathway with a lower activation energy.
* Enzymes are biological catalysts, usually proteins, that facilitate specific biochemical reactions. They are highly specific in their actions, meaning they only work on certain molecules.
* Other catalysts can be inorganic substances like metals, acids, or bases. These are often used in industrial processes.
Here's an example:
* Enzymes in your digestive system break down food molecules into smaller units that your body can absorb. However, the enzymes themselves remain unchanged throughout the process.
Key Features of Catalysts:
* Speed up reactions: Catalysts lower the activation energy needed to start a reaction, making it happen faster.
* Remain unchanged: Catalysts are not consumed in the reaction and can be used repeatedly.
* Specific: Catalysts often only work with specific reactants or reactions.
