Biology Coursework on Catalyse

Introduction An enzyme is a is one of many specialised organic substances intentional to act as a catalyst to charm the localize of the many chemical receptions that done in the human body, enzymes argon classified into many major categories these include hydrolytic, oxidising and reducing depending on what part of a reaction they play.         Enzymes specifically atomic egress 18 large proteins that speed up chemical reactions in the body, they do this by bringing to hold fasther a small number 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 tinted(p) by the reaction. After having taken place the enzyme is ready to cling again with a new substrate. The curl and Key conjecture 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 hav e an appropriate molecular send off so that substrate grassnot 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 pull up stakesing be unable to fit in the lock cause no reaction, heretofore if the correct substrate is used then(prenominal) the key will fit and a reaction will top. 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 reactions oc curs. For example temperature is extremely ! valuable 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...
