1 Definition

Metabolism is defined as the transport and the chemical transformation of substances within an organism. The enzymes, which catalyze chemical reactions, are essential for the metabolism.

2 Examples

3 Plants

For example during photosynthesis, using the energy radiated from light, metabolic processes transform carbon dioxide (mostly stemming from the air), water and other source materials into other substances that either immediately serve the construction and growth of the organism or are stored.

4 Animals

Animals metabolize other organisms or their stored substances during their digestion (eg. Proteins during the protein metabolism, fats during lipid metabolism, or carbohydrates during carbohydrate metabolism).
