In biology, enzymes are generally described as what type of substance, given their role in speeding up chemical reactions within living organisms?

Explanation

Enzymes are generally described as biological catalysts, meaning specialized proteins that significantly speed up the rate of specific chemical reactions occurring within living organisms, without being permanently consumed or fundamentally altered by the reactions they help facilitate. Each specific enzyme typically works on a particular type of chemical reaction or molecule, allowing the body to precisely regulate an enormous range of essential biochemical processes, from digestion to energy production. Enzyme activity can often be affected by factors such as temperature and pH, which is why enzymes generally function best within a fairly specific and relatively narrow range of conditions.
