Verified step by step guidance

Understand the First Law of Thermodynamics, which states that energy cannot be created or destroyed, only transformed from one form to another.

Identify the types of reactions listed: Exergonic, Endergonic, Adiabatic, and Isothermal.

Exergonic reactions are characterized by the release of energy. This energy can be used by cells to perform work, making them relevant to the question.

Endergonic reactions require an input of energy to proceed, which is opposite to what the question asks for.

Adiabatic and Isothermal reactions are terms related to thermodynamics processes, not directly related to energy release for cellular work. Adiabatic involves no heat exchange, and Isothermal involves constant temperature.
