Engineering HSC and IIT-JEE Mains and
Advanced videos. hello students today
will be studying chapter biochemistry of
self in that we'll be studying topic
properties of enzymes
now when I say properties enzymes work
at certain parameters there is a
definite way by which enzymes work and
if that way is not followed out enzymes
bond function today we'll be studying
that pathway by which enzymes work .
properties of ezymes. now enzymes worked in a
certain fashion and there are various
properties of an enzyme first one could
be enzymes are needed in small
quantities for a reaction enzymes do not
accelerate the reaction they actually
fashion of the reaction or enzymes
substrate initiate the reaction there is
a site called as the site where the
substrate comes and binds the enzyme
substrate does not what binds anywhere
else on the enzyme enzymes never change
their shape during the reaction or
during the process of chemical reaction
enzymes have optimum temperature for
working or enzymes work at certain
optimum for example if you are using XEL
it will work at room temperature but
when you are considering an enzyme that
works in human body it will definitely
work at 37 degree Celsius since the
temperature in your body is 37 degree
Celsius enzymes are needed in small
quantity the reason for this is that
whenever enzymes are formed inside a
body they are used continuously and they
do not change their shape so there is no
need to use enzymes or to synthesize
enzymes rapidly so this was certain
properties of enzymes
moreover enzymes are specific in nature
when I say specific in nature it means a
certain enzyme will be available for a
certain substrate for example pepsin
works on proteins only during the
process of digestion pepsin will be used
for protein digestion catabolism or
anabolism for glucose or for
carbohydrate digestion there will be
some another enzyme every enzyme has a
particular substrate and a particular
reactant this is how enzyme works so let
us see the properties of enzymes
[Applause]
properties of enzyme enzymes they are
needed in small quantities they do not
change their shape during a chemical
reaction the shape of an enzyme and its
active site remains as it is it never
changes they accelerate but do not
initiate the reaction when I say
accelerate it means enzymes fast enough
the process of a reaction but substrate
is a thing that any shape all starts the
reaction enzymes are specific in nature
for a particular substrate there will be
a specific enzyme
substrate or the substance which reacts
with the enzyme binds on the active site
of an enzyme active site is a place
where the enzyme accepts the substrate
and forms the product enzymes have
different Optima when I say Optima it
means enzymes have different
temperatures at which they work an
example of this could be axial works at
room temperature and pepsin works at 37
degrees Celsius and if you change the
temperature of a particular enzymes the
enzyme group denature or get destroyed
so students in this part of the topic we
have studied what are the various
properties of enzymes and how enzymes
function I hope you all have understood
the various properties of an enzyme
thank you
