More specifically, in biological systems, we call these catalysts enzymes. Enzymes are proteins that act as biological catalysts, facilitating and speeding up chemical reactions in living organisms without being consumed in the process.
Here are some key characteristics of catalysts and enzymes:
* Speed up reactions: Catalysts lower the activation energy required for a reaction to occur, making it happen faster.
* Remain unchanged: Catalysts are not used up in the reaction and can be reused.
* Specific: Enzymes are highly specific to their substrates (the molecules they act upon) and catalyze only certain reactions.
