This episode will discuss metabolism.

Metabolism encompasses all chemical processes within living organisms. It involves enzyme-assisted reactions that synthesise new molecules. 

These reactions include the conversion of glucose into storage compounds like starch and glycogen. Lipid formation occurs through combining glycerol and fatty acids. 

Additionally, glucose and nitrate ions combine to produce amino acids, the building blocks of proteins. The breakdown of surplus proteins leads to urea production, subsequently removed from the body as urine.
