Making the world better, one answer at a time. Enzymes act as catalysts, and they almost always affect a specific reaction. Enzymes are proteinaceous biocatalysts that catalyze chemical reactions occurring in the living cell. Enzymes act as catalysts, and they almost always affect a specific reaction.<br /><br />
How Enzymes work. 1. Enzymes catalyse only those reactions that happen naturally. 2. Enzymes are specific: each enzyme is responsible for only 1 kind of reaction, because they are shaped to work with only a certain substrate that matches enzyme's active site. 3. Enzyme changes its conformation when substrate bonds to its active site.
