Biology Coursework on Catalyse

Introduction An enzyme is a is one of many specialised thoroughgoing substances intentional to act as a catalyst to tone the localize of the many chemical receptions that done in the kind-hearted body, enzymes argon classified into many major categories these include hydrolytic, oxidising and cut depending on what part of a reaction they play.         Enzymes specifically be large proteins that speed up chemical reactions in the body, they do this by bringing to hold fasther a small round of aminic acids for form the ready site (the location on the enzyme where the substratum declares and the reaction takes place (see lock and report theory)) the enzyme itself in un altered(p) by the reaction. After having taken place the enzyme is ready to perplex again with a new substrate. The curl and Key speculation The Lock and Key theory says that when the substrate attempts to bind with an enzyme at the active site that the enzyme and the substrate have a n appropriate molecular send off so that substrate croupenot join on to an enzyme that it is not suppose to.

In essence this give a lock and key if the incorrect substrate attempts to bind with a enzyme it allow for be unable to as the key depart be unable to fit in the lock create no reaction, heretofore if the correct substrate is used therefore the key impart fit and a reaction will sink. This prevents the incorrect substrate reaction with an enzyme. Properties of Enzymes Enzymes are organic and can therefore be denatured, and the surrounding environment can affect the rate in which their various reac tions occurs. For example temperature is ext! remely important in the process, if the temperature is to a fault high the enzyme will be denatured, and if the temperature is too low the reaction will not occur or will...
