Here's why:
* Carrier Molecule: Enzymes bind to specific molecules called substrates. They act as carriers, bringing the substrates together in the correct orientation for the reaction to occur.
* Facilitating Chemical Reactions: Enzymes lower the activation energy of reactions, making them happen faster. They do this by providing an alternative pathway for the reaction to occur.
Key points about enzymes:
* Specificity: Each enzyme has a specific active site that only binds to certain substrates.
* Catalysts: Enzymes are biological catalysts, meaning they speed up reactions without being consumed in the process.
* Proteins: Most enzymes are proteins, but some are RNA molecules (ribozymes).
