Metabolism Quiz

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.
