Q:Answer the following question given this paragraph: Chemical reactions that release energy are called exothermic reactions . An example is the combustion of methane described at the beginning of this lesson. In organisms, exothermic reactions are called catabolic reactions . Catabolic reactions break down molecules into smaller units. An example is a decomposition reaction, such as the breakdown of glucose molecules for energy. Exothermic reactions can be represented by the general chemical equation:. Q: What type of reactions are chemical reactions that release energy? Choices: - sulfuric reactions - biochemical reactions - ozonic reactions - exothermic reactions A:
A:
exothermic reactions
