Cellular Energy and Thermodynamics Quiz

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.
