Final answer:
The reaction that releases energy is an exergonic reaction option (c), which in biological contexts, is typically associated with catabolic reactions that break down molecules and release energy.
Step-by-step explanation:
The reaction that releases energy among the options provided is exergonic. In biological terms, catabolic reactions are typically exergonic, meaning they release energy by breaking down larger molecules into smaller, simpler molecules.
Both cellular respiration and the breakdown of glucose during cellular respiration are examples of catabolic, exergonic reactions that release energy. In contrast, anabolic reactions, including photosynthesis, are endergonic because they require the input of energy to build larger molecules from smaller ones.
