Reactions in chemical bonds

WebJan 30, 2024 · When a chemical reaction occurs, molecular bonds are broken and other bonds are formed to make different molecules. For example, the bonds of two water molecules are broken to form hydrogen and oxygen. (1) 2 H 2 O → 2 H 2 + O 2 Energy is always required to break a bond, which is known as bond energy. WebA substance that speeds up a chemical reaction—without being a reactant—is called a catalyst. The catalysts for biochemical reactions that happen in living organisms are called enzymes. Enzymes are usually proteins, though some ribonucleic acid (RNA) molecules act as enzymes too.
