what does amalyse do
amalyse breaks down
starch
into
glucose
what doe starch do to iodine
starch turns iodine to
blue
experiment
use a place only one drop of
iodine
in a spotting dwell
prepare different ph of
buffer solution
and
amalyse
and mix together
transfer
starch
in solution and mix the contents together as well
use continous sampling via a
clock
for a set time period and use a
pipette
to place a drop of the mixed solution into spotting dwell
record how long it takes for iodine to turn
blue
what is the control variable In the experiment
volume of
amylase
solution and volume of
starch
solution
what is the independent variable
the
pH
of buffer solution
what is the dependant variable
the time it takes for
iodine
to remain orange/
starch
to be broken don
what is the quickest pH for starch to be broken down mean
it's the
Optum
pH
why does some pH take longer for starch to be broken down then othersor if there's no change in iodine colour
amalyse active site denatures meaning no enzyeme substrate complex can be formed as starch can't bind to the active site
