Key Concepts

Endothermic Reaction

An endothermic reaction absorbs energy from its surroundings, meaning it requires an energy input to proceed. In biological systems, such reactions commonly occur when the cell invests energy to synthesize complex molecules or drive non-spontaneous processes.

Exothermic Reaction

An exothermic reaction is a process that releases energy, often in the form of heat, to its surroundings. In biochemical pathways, these reactions provide the energy needed for various cellular functions, and their spontaneous nature helps drive other energy-requiring processes.
