Catabolic

Definition

Catabolic processes involve the breakdown of complex molecules into simpler ones, releasing energy. These reactions are crucial for cellular respiration and energy production in living organisms.

5 Must Know Facts For Your Next Test

1. Catabolic pathways release energy by breaking down larger molecules like carbohydrates, fats, and proteins.
2. The energy released during catabolic reactions is often captured in the form of ATP (adenosine triphosphate).
3. Examples of catabolic processes include glycolysis, the citric acid cycle, and oxidative phosphorylation.
4. Catabolism is essential for maintaining cellular functions and providing building blocks for anabolic reactions.
5. Hormones like cortisol and adrenaline typically stimulate catabolic pathways.
