The term enzymes, was first used in 1878. the term is derived from a greek word that means in yeast because the yeast cells were first to reveal enzyme activity in living organisms. what do you know about the physical and chemical properties of enzymes?

each enzyme can function under a wide range of temperature and ph conditions within the human body.
nearly all enzymes are proteins, although a few catalytically active rna molecules have been identified.
enzymes are not highly specific with respect to substrates and can be used interchangeably.
enzymes are catalysts that increase the rate of a chemical reaction without being changed themselves in the process.
many enzymes require the presence of small, non-protein units or cofactors to carry out their particular reaction.
