what are
enzymes
?
enzyme increase the reaction of speed
they are often called biological
catalysts
what is the active site?
for the reaction to speed,the
subtrate
only bends to specific
enzymes
what are factors that affect the rate of
enzymes
?
pH-have an
optimum
of pH,if the pH changes away from the optimum pH,then the enzyme decrease,if the pH is to high or low the enzyme will denature
temperature-enzymes have a optimum temperature,if it past the temperature the
active site
will change the shape and the enzyme will denature
what are
enzymes
in digestion?
are produced by
specialised
cells
they are situated in the
glands
and the lining of the gut
they are then secreted out of the body cells and into the cavity of the digestive system
how do the
enzymes
breakdown
large food molecules?
the
digestive enzymes
catalyse
a large amount of food into smaller molecules of food
then they are absorbed into the bloodstream
digested molecules can be used to construct new
carbohydrates
,proteins and
lipind
in the body
what are the 3
main
enzymes
in the body?
amylase
protease
lipase
what is amylase?
amylase is a type of
carbohydrase
that breaks down
starch
where is the
amylase
site?
the small
intenstine
the mouth
where is
amylase
producted in?
small intenstine
pancreas
salivary glands
what is the amylase purpose?
when amylase breaks down the starch,maltose and other sugars are produced
what are
protease
?
protease are digestive
enzymes
that breaks down
proteins
into
amino acids
what are protease purpose?
protease breaks down into
amino acids
where are
amino acids
produce in?
small intenstine
stomach
pancreas
what are
action site
of
protease
?
small intenstine
stomach
what are lipase?
is a type of
enzymes
that breaks down
lipids
into glycerol and
fatty acids
where are
lipase
production?
small intenstine
pancreas
what is bile?
bile is an
alkaline
substance produced in the
liver
and stored in the
gallbladder
why are
bile
important?
enzymes
in the small intentistine operates the best in
alkaline
condition
stop enzymes to
denature
by neutralising the
stomach acid
what is
emulsification
?
bile
breaks up fats into tiny droplets
the tiny droplets have a high surface area
this increase the rate of
lipase
