What Factors Affect the Speed of Chemical Reactions?

WebA catalystis a chemical that speeds up chemical reactions. In organisms, catalystsare called enzymes. Essentially, enzymes are biological catalysts. Like other catalysts, enzymes are not reactants in the reactions they control. They help the reactants interact but are not used up in the reactions. Instead, they may be used over and over again. WebAn enzyme is when it loses its native conformation and its biological activity. 2. An enzyme is considered a because it speeds up chemical reactions without being used up. 3. An enzyme is considered because of its ability to recognize the shape of a particular molecule. 4. A , such as a vitamin, binds to an enzyme and plays a role in catalysis. 5. WebA catalyst is a substance that speeds up a chemical reaction, or lowers the temperature or pressure needed to start one, without itself being consumed during the reaction.
