Study Notes
Energy Types
- Kinetic energy is the energy of motion.
- Potential energy is the energy stored in the location or structure of matter.
Laws of Thermodynamics
- The laws of thermodynamics state that energy cannot be created or destroyed, only transferred or transformed.
- During energy transfers or transformations, some energy is lost as heat and becomes unavailable to do work.
Energy Reactions
- Exergonic reactions are reactions that release energy.
- Endergonic reactions are reactions that require energy and yield products rich in potential energy.
Cellular Work
- ATP (Adenosine Triphosphate) drives cellular work by coupling exergonic and endergonic reactions.
- This coupling allows cells to harness energy released from exergonic reactions to drive endergonic reactions.
Cellular Metabolism
- Metabolism encompasses all of a cell's chemical reactions, including energy-releasing and energy-requiring reactions.
- Cellular metabolism is driven by the coupling of exergonic and endergonic reactions.
