Enzymes: Enzymes are proteins that act as catalysts in biochemical reactions. They are present in all living things and are necessary for life. Enzymes are highly specific, meaning they only catalyze certain types of reactions.
Metals: Metals are often used as catalysts in chemical reactions. They can provide a surface on which reactants can bind, which can make it easier for reactions to occur. Metals can also be used to form complexes with reactants, which can also make reactions easier to occur.
Acids and Bases: Acids and bases are also used as catalysts in chemical reactions. They can donate protons or hydroxide ions, which can react with the reactants to make the reaction easier.
Light: Light can also be used as a catalyst for certain chemical reactions. This is called photocatalysis. In photocatalysis, light energy is used to break down molecules, which can then react with other molecules to form new products.
Catalysts are an important part of many chemical reactions. They can speed up reactions, improve efficiency, and produce desired products.
