Study Notes
Metabolism
- The sum of all chemical reactions that occur within a living organism.
Exergonic Reactions
- Reactions that release energy.
ATP's Role in Energy Transfer
- ATP acts as an energy carrier, transferring the energy released from exergonic reactions to drive endergonic reactions.
Biochemical Thermodynamics
- The study of energy changes accompanying biochemical reactions.
Energy Liberation in Biochemical Reactions
- Most often liberated in the form of heat.
Laws Governing Biological Energy Transformations
- Biological energy transformations obey the laws of thermodynamics.
First Law of Thermodynamics
- States the principle of conservation of energy, meaning energy can neither be created nor destroyed but can be transferred from one form to another.
Closed System
- Includes everything within a defined region of space, and there is no exchange of energy or matter with its surroundings.
