Study Notes
Biosynthetic Processes
- Anabolism is the process that involves the synthesis of biomolecules from simpler components.
Energy Source for Biosynthesis
- The major free energy source for biosynthetic processes is ATP (adenosine triphosphate).
Intermediates in Biosynthesis
- Activated carriers, such as ATP, NADH, and FADH2, serve as starting materials for a variety of biosynthetic products.
Metabolic Process
- The overall process of metabolism involves the conversion of energy and nutrients from one form to another to maintain the living state of an organism.
Metabolic Pathways
- Metabolic pathways are defined as a series of enzyme-catalyzed reactions that convert one molecule into another.
Categories of Metabolic Pathways
- Metabolic pathways are often divided into two categories: catabolic pathways (breakdown of molecules to release energy) and anabolic pathways (synthesis of molecules to store energy).
Maintaining Living State
- Living systems couple the exergonic reactions of nutrient oxidation (energy-releasing reactions) to the endergonic processes (energy-requiring reactions) required to maintain their living state.
