Reactions where chemical bonds are broken, releasing the energy in those bonds, are often exergonic reactions.
Explanation:
Reactions where chemical bonds are broken, releasing the energy in those bonds, are often exergonic reactions. These reactions where chemicals are broken down are called “catabolism” – the destructive part of metabolism. By contrast, reactions where chemical bonds are formed are often endergonic.
