Metabolism is a term that most people probably know, but do you know just exactly what metabolism is? It's the process by which living creatures chemically change and create substances. On a cellular level, life works like a chemical plant. Animals are capable of producing over 3,000 different substances while plants can produce nearly 200,000. Today, we focus on a few of the substances that play a key role in metabolism. First, an oil made by algae that could be used as a new bio-fuel. It was even used to fly a jet plane. Next, a substance that is used to produce a drug for treating pancreatic cancer. But that's not all! Tune in to learn more about the newest research on the amazing mechanisms of living things and how they can help create new kinds of energy and medicine.
