Catabolism
Definition
Catabolism is the process by which the body breaks down complex molecules into simpler ones, releasing energy that can be used by the body.
Scientific / Technical Definition
Catabolism is a metabolic pathway that involves the breakdown of complex molecules such as carbohydrates, lipids, and proteins into smaller units like sugars, fatty acids, and amino acids. This process releases energy stored in these molecules, primarily in the form of adenosine triphosphate (ATP), and is crucial for maintaining cellular activities.
Benefits
- Provides energy necessary for physical activity and bodily functions.
- Helps in repairing and maintaining tissues by breaking down damaged components.
- Supports the elimination of excess compounds by transforming them into forms that can be expelled by the body.
Examples
- During exercise, glucose undergoes catabolism to produce energy.
- Catabolism of fats resulting in fatty acids that can be used for energy production.
Additional Information
- Effects: Catabolism breaks down larger molecules into smaller ones, releasing energy and providing building blocks for bodily functions.
