Verified step by step guidance

Understand the definitions of catabolic and exergonic reactions: Catabolic reactions involve the breakdown of larger molecules into smaller ones, while exergonic reactions release energy during the process.

Recall that breaking covalent bonds is a key feature of catabolic reactions. For example, during glycolysis, glucose is broken down into smaller molecules, releasing energy.

Recognize that breaking covalent bonds releases energy, which aligns with the exergonic nature of the reaction. This energy can be used for cellular processes like ATP synthesis.

Eliminate the incorrect options: 'form' refers to anabolic reactions, which build molecules; 'strengthen' and 'stabilize' do not describe the energy-releasing process of breaking bonds.

Conclude that the correct answer is 'break,' as catabolic and exergonic reactions typically involve breaking covalent bonds to release energy.
