Reactions that release energy are called __________ reactions.

Verified step by step guidance

1. Identify the type of reaction based on energy changes.
2. Understand that reactions can either absorb or release energy.
3. Recall that reactions releasing energy are often associated with breaking down molecules.
4. Consider the term used for reactions that release energy, often related to catabolic processes.
5. Recognize that these reactions are typically exothermic, releasing energy in the form of heat or light.

Key Concepts

Exergonic Reactions

Exergonic reactions are chemical processes that release energy, typically in the form of heat or light. These reactions occur spontaneously and are characterized by a negative change in Gibbs free energy. An example of an exergonic reaction is cellular respiration, where glucose is broken down to release energy for cellular activities.

Thermodynamics

Thermodynamics is the branch of physics that deals with heat, work, and energy transformations. In microbiology, understanding thermodynamics is crucial for analyzing metabolic pathways and energy exchanges in living organisms. The laws of thermodynamics help explain how energy is conserved and transformed during biochemical reactions.

Metabolism

Metabolism encompasses all chemical reactions that occur within a living organism to maintain life. It includes catabolic reactions, which break down molecules to release energy, and anabolic reactions, which use energy to build complex molecules. Understanding metabolism is essential for grasping how organisms utilize energy from their environment.
