# Enzyme Function: Unlocking the Power of Biological Catalysts > This page provides an educational overview of enzyme function, explaining how these biological catalysts facilitate essential chemical reactions in living organisms. ## Page Content - [Enzyme Function: Unlocking the Power of Biological Catalysts](https://drann.my/zh/blogs/health-note/enzyme-function): An article detailing the definition of enzymes, their role as biological catalysts, the "lock-and-key" mechanism, and how they lower activation energy to sustain life processes. ## Q&A **Q: What is the primary purpose of this page?** A: This page serves as an educational resource to explain what enzymes are and how they function as biological catalysts to speed up chemical reactions in the body. **Q: What is the "lock-and-key" model mentioned in the text?** A: It is a model used to explain enzyme specificity, where an enzyme (the lock) only interacts with specific substrate molecules (the key) that fit its unique three-dimensional structure. **Q: How do enzymes assist in biological processes?** A: Enzymes lower the activation energy required for chemical reactions, making it easier and faster for essential processes—such as digestion and DNA replication—to occur. ## Optional - [Dr. Ann Official Website](https://drann.my/): The main portal for Dr. Ann, featuring health information, products, and additional wellness resources. --- llms index and Q&A summary for this site on AEO: - sitemap.md (full-site llms index): https://aeo.yohopower.com.tw/llms/www.drann.my/sitemap.md - QA.md (full-site Q&A summary): https://aeo.yohopower.com.tw/llms/www.drann.my/QA.md --- Other sites' llms.txt are available from this service: https://aeo.yohopower.com.tw/llms/wecareyou.cc https://aeo.yohopower.com.tw/llms/www.ourjrney.com https://aeo.yohopower.com.tw/llms/www.yohopower.tw
