They are unique in that they have the ability to respond to multiple different conditions in their immediate environment. These are called allosteric sites, and enzymes can have more than one. That is, they help to accelerate the rate of a reaction, but remain unchanged during the entire process.Īllosteric enzymes are enzymes which have an additional site, as well as the active site – it comes from the Greek ‘allo’, which means ‘other’.
