Study Notes
Energy and Metabolism
- The energy currency of life is ATP (Adenosine Triphosphate).
- In a series of reactions, molecules are degraded or synthesized, known as cellular respiration or metabolism.
ATP Production
- The primary source of ATP production is cellular respiration, which occurs in the mitochondria.
Regulation of Metabolic Pathways
- Metabolic pathways are regulated by allosteric control, substrate inhibition, and energy status of the cell.
Catabolism
- The main purpose of catabolism is to break down molecules to release energy, which is then used to generate ATP.
Anabolism
- Anabolism is characterized by endergonic reactions, which require energy to synthesize new molecules.
Energy Exchange
- Coenzyme A (CoA) is the energy exchanger linking catabolism and anabolism.
Exergonic Reactions
- The energy state of the initial compounds in exergonic reactions is high energy, resulting in a spontaneous release of energy.
