Answer:
The best biological term to describe a chain of enzyme controlled reactions is metabolic pathways. Metabolic pathways are a series of enzyme-catalysed reactions that convert a substrate into a product. These pathways are essential for the metabolic processes of living organisms, and are usually regulated by a complex network of enzymes and other regulatory proteins. Phosphorylation pathways involve the transfer of phosphate groups from one molecule to another, and enzyme metabolism is a term used to describe the chemical changes caused by enzymes.
