Metabolism - derived from the Greek μεταβολή (metabole): to change - denotes a multitude of chemical processes that take place in living cells. In the course of these processes, substances are converted - that is, changed.
These processes allow organisms to maintain their structure, to grow, to reproduce, to move, and to respond to stimuli from the environment - in other words: to fulfill the characteristics of life.
The topic of metabolism is about understanding how and where the most important of these life-supporting processes take place, what requirements they need, what general mechanisms “mother nature” has in her “bag of tricks,” and how these processes are related.
Sounds complex? It is ... and exciting. After all, the topic of metabolism allows us to understand where and how we get the energy we need to explore our world and live in it.
