Catabolize

To catabolize means to break down complex molecules into simpler ones within a living organism, typically in order to release energy. This process is essential in metabolism, where the body converts food into usable energy and building blocks for cellular processes. Catabolism is contrasted with anabolism, where simple molecules are used to create more complex structures. This term is derived from 'catabolism,' a key aspect of metabolic pathways.

Catabolize meaning with examples

• After a long workout, the body begins to catabolize stored glycogen to provide energy to the muscles. This breakdown is crucial for sustaining strength and endurance during physical exertion, allowing athletes to improve performance and reach their fitness goals without depleting their energy reserves entirely.
• During prolonged fasting, the human body will catabolize fat stores to maintain energy levels. This metabolic shift helps preserve essential functions while forcing the body to adapt to limited food intake. As a result, individuals may experience significant weight loss as fat is utilized for energy.
• In research on cellular metabolism, scientists found that cancer cells often catabolize glucose at a much higher rate than normal cells. This heightened catabolic activity provides the energy and building blocks necessary for rapid cell division and tumor growth, making it a target for therapeutic interventions.
• Enzymes in the digestive system catabolize food into essential nutrients and energy sources. This process begins in the mouth and continues in the stomach and intestines, illustrating how effectively the body can utilize and transform complex dietary components into simpler forms.
• When organisms experience stress, they may catabolize protein to support crucial biological functions. This reaction highlights how the body prioritizes survival over muscle preservation, often resulting in muscle loss during severe illness or malnutrition.
