What is an enzymes function, how does it work,
and what do we mean by calling it a biological catalyst?
Well, there certainly is a lot to this question! A catalyst is the
name given to something which speeds up a chemical reaction but
does not take any part in the reaction. The catalyst can be recovered
once the reaction is over. Biological catalysts is the name given
to catalysts in living cells. These are called enzymes and they
are all protein molecules. An enzyme is specific - which means that
it will only accelerate one particular reaction. Imagine how many
different enzymes there must be! One of the most well-known enzymes
is called salivary amylase. Try searching for this enzyme to find
out where it is found in your body and which reaction it is needed
for. Most enzymes work by bringing the chemicals which are reacting
closer together on the surface of the enzyme. Try looking up the
"Lock and Key" hypothesis to find out more about how this works.
Good luck
