Study Notes
Gibbs Free Energy
- Gibbs Free Energy indicates a system's capacity to perform work; it is a measure of the energy available from a thermodynamic system.
- True statement: Gibbs Free Energy can drive reactions in a system.
ATP Hydrolysis
- Hydrolysis of ATP is an exergonic reaction that releases energy, which can drive various endergonic reactions within the cell.
Anabolic Pathways
- Anabolic pathways focus on synthesizing complex molecules from simpler ones, contributing to cellular growth and repair.
- Examples of anabolic processes include:
- Growth of fat cells during periods of plenty.
- Synthesis of new DNA copies before cell division.
Entropy and Anabolism
- Anabolic reactions result in decreased entropy in the system due to the formation of more ordered structures, such as macromolecules.
Chemical Reactions in Metabolism
- Protein synthesis represents an endergonic and anabolic chemical reaction, requiring energy input to build complex proteins.
Catabolic Reactions
- Catabolic reactions are characterized as exergonic, meaning they release energy, and exhibit a negative change in free energy, contributing to the overall energy balance in metabolism.
