explain why enzymes have an optimum ph
if its too high or too low it interferes with the enzyme bonds and denatures the cell
1 of 5
changing the temperature changes the rate of of an enzyme-catalysed reaction
all enzymes have a optimum temperature and ph
2 of 5
enzymes have special shapes so they can catalyse reactions
every enzyme has an active site where the catalysed reaction takes place
3 of 5
an increase of temp over 40 degrees causes changes to the enzyme
therefore the enzyme becomes denatured and no longer func§tions
4 of 5
enzymes have a high specifity for there substrate
for the enzyme to worth substrate has to fit into the active site, if it does not match then the reaction will not be catalysed this is called the lock and key method
