Types of Respiration, CBSE Class 11 Biology Video Lecture

good day students today we are going to
talk about topic respiration now before
talking about respiration we should know
what is whiter or what are being vital
activities so the vital activities can
be defined and the physical chemical
processes which are taking place inside
this cell or living organisms vitamins
very important or very effective
you
so the vital activities can be defined
as the physico-chemical all the physical
chemical activities of a cell or deliver
gamma
you
as we all know that vital activities are
very essential for life
you
you are must have heard about her when
moved on that is called as meta bond
isn't so since you have an idea about
the vital activities so the matter of
autism can be defined as see all these
sum total of violent activities
you
so now we have idea about a brief idea
about the vital activities which are the
physical chemical activities of a cell
and metabolism all the Viper activities
or the processes of occurring inside a
cell which are very essential for the
survival of a self now the metabolism
word can be or the metabolism of a cell
can be categorized into two groups means
the processes vital activities or the
chemical reactions or the physical
chemical reactions basically can be
basically categorized into two
categories that is the catabolism and
the antagonism
in simple terms the catabolism can be
defined as the breakdown processes
and the anabolism can be defined as the
synthesis across
now what does this mean the breakdown
process and synthesis process the
breakdown process can be defined as the
process in which the breakdown of large
complex molecules into simpler
substances offers example the
respiration process
you
while in synthesis process as we all
know that synthesis occurs from simpler
substances to form the large complex
molecules so it is just opposite of the
catabolism and the example is
photosynthesis process
you
now after this basic difference when
more difference can be cited in case of
catabolism since there is a breakdown
process generally the ATP molecule that
is the energy currency of the cell or on
living organism is synthesized or
produced
but in case of cannibalism as I have
said earlier also that it is just
opposite of the catabolism so since
their EVPs produced so in anabolism that
is synthesis process ATP is required or
is utilized
since we all know that for all the
synthesis process but whatever we are
synthesizing we require energy so the
example of catabolism is respiration
that we are going to study in detail
and example of anabolism is the
photosynthesis process you must be
knowing where the photosynthesis process
occurs it occurs in the green plants and
some bacteria and algae now coming back
to our main topic that is respiration
you
first of all about its definition means
how this process this data Bolling
process can be defined the respiration
can be defined as the catabolic process
Oh breakdown
the breakdown can also be called as the
oxidation or burning
break down off the assimilated home
like glucose
to release the energy
I hope you must be knowing what is the
assimilated food after the digestion of
food it is absorbed by the blood and
transported to every cell of the body
when it is being absorbed by the cells
and utilized it is called as
assimilation so the assimilated food
which is in simplest form like glucose
is broken down or oxidized or burned to
produce the energy now this energy is
stored in the form of ATP
because ATP as I have said earlier also
that ATP the energy cannot currency of
the living cells they can utilize the
ATP formed during this process for any
of the other metabolic processes besides
the ATP certain other byproducts are
also formed which include the co2 that
is carbon dioxide and water vapor water
in the form of water vapor
you
these two end products that is carbon
dioxide and water vapor are the base
products so they need to be eliminated
of the body to the glass
you
if you write equation on this process or
to present this process in the equation
form it is as follows that is the raw
material physical which gets oxidized
to form the end products which includes
carbon dioxide water and the energy ATP
which is further utilized worthy life
processes or the metabolism in this
reaction if we add the oxygen then it
becomes the aerobic respiration which
means if food is oxidized in presence of
the oxygen then it will be called as the
aerobic respiration but if this
oxidation process occurs in absence of
oxygen it is gone diathi anaerobic
respiration we'll discuss them in detail
later on now let us discuss the types of
respiration
just mention a world that the
respiration can be divided into two
types on the basis of the requirement of
oxygen so it can be either the aerobic
respiration
you
as shown in the verve reaction the food
is oxidized if it is oxidized in the
presence of oxygen it is called as
aerobic respiration
you
broadly the aerobic respiration and
represented in the equation form as
follows in the first step the food is
broken down to produce the product that
is called as pyruvic acid and the
process or the first step is called as
glycolysis
this term express in the cytoplasm of
the cell in absence of the oxygen so no
oxygen is required for the forces then
the next step is called as the kreb
cycle kreb cycle is named after the
scientist who discovered this pathway
and this process that is kreb cycle
occurs in the mitochondria offi
and this step requires oxygen so it
occurs in presence of
and the final products are the co2 six
molecules of carbon dioxide six
molecules of water vapor water in the
form of what went wrong and 38 molecules
of ATP which is equivalent to 673 kilo
calories of energy the food which is the
raw material for the respiration process
can be the simplest form that is real
force now the second type of the
respiration is called as the anaerobic
respiration
as the name implies this process that
has oxidation of food occurs in absence
of oxygen
you
in the equation form this anaerobic
respiration can be represented as it
again it will start with the food as in
case of the aerobic respiration like
glucose sip this one the first step is
common which leads to formation of the
pyruvic acid and it's called as
glycolysis
which takes place in cytoplasm in
absence of oxygen so we can say that the
glycolysis process is the universal
process of cellular respiration whether
it is the aerobic respiration or the
anaerobic respiration now from the
pyruvic after formation of the pyro
mckesson
this spiral cancer which is formed after
the first step can undergo different
processes and lead to formation of
different types of products so in case
of anaerobic respiration there is no
single representation it depends upon
the different type of organic on
sandwiches is anaerobic respiration is
taking place here i am representing the
two types of the anaerobic respiration
one which takes place in the east
and this leads to the formation of the
pile alcohol as the product
two molecules of the tile alcohol to
minors of co2 and two ATP molecules
the second type of anaerobic respiration
in which the perak acid undergoes
deformation of lactic acid and this
takes place in the muscle cells of the
higher animals during vigorous exercise
you
in this process the potomac acid
undergoes the process and leads to
formation of the tactic acid and two
molecules of as ATP
as you can see that in case of lactic
acid formation low carbon dioxide is
formed as the end product the process or
the anaerobic respiration which is
taking place inside the key step is also
called as the population
commendation means moment means to Froch
that is formation of fraud so
combination is the type of anaerobic
respiration which is used in large scale
at the large scale in the beverage
industries for the formation of alpha
boy and this rock formation is due to
the production of carbon dioxide
molecule which when it was it leads to
formation of the bubbles or the rock now
let us define the fermentation process
it can be defined as the anaerobic
respiration
which takes place inside deep microcosm
like the East cells bacteria and other
fungi now if the lactic acid pathway
that is formation of lactic acid by
anaerobic respiration occurs inside a
microorganism then it can also be termed
as the fermentation process but if
lactic acid formation is taking place
inside the muscle cell of an higher
organism during the vigorous exercise
then it cannot record as fermentation it
pretty simply called as the anaerobic
respiration so condition for being
categorized as the fermentation is that
it should take place that is the
anaerobic respiration that should take
place in the microorganism now coming to
the steps of respiration inspiration as
I have written in the equation form is
not that simple that means it does not
occur in a single step or two step it is
a multi-step process so it is divided
into several steps
broadly the respiration process is
divided into three steps
you
which includes the external respiration
it is the exchange of gases like co2 and
oxygen between the organism and its
external environment
you
as we all know that oxygen is required
giving the Arabic respiration and co2 is
e that as carbon dioxide is the end
product of a cellular respiration be or
the second step is the internal
respiration the external respiration can
also required as the breathing process
you
the next step or the second step is the
internal respiration
internal respiration and was that
process in which there is the exchange
of gases between the tissue cells and
the extracellular and one
gases are the same that is carbon
dioxide and oxygen
you
the extra single arm and can be the
extracellular fluid black are we playing
the last step is the cellular
respiration
this cellular respiration is the process
which up which takes place at the
cellular level which means the actual
observation of food which takes place
inside the cell to release the energy
you
out of these three steps the first and
the second step that is the external
respiration of breathing and the
internal respiration can be different
among the different organisms that is
the mechanism of internal and external
respiration can be different among the
different organisms like plants respire
differently the lower animals respire
differently and the animals human beings
and other higher animals use different
organs for the external respiration but
in case of the cellular respiration it
is the same or the universal process
that will occur in these cells that is
either by the aerobic process or the
anaerobic process so it is a short step
which is common or universal among all
the organisms and it can happen in two
forms that is aerobic respiration or the
anaerobic respiration now let us discuss
in brief the major differences which are
between the external respiration that is
breathing and the cellular respiration
you
breathing is the process of exchange of
gases that is co2 and oxygen between the
organism and its environment so it can
be categorized as a physical process
whereas in case of cellular respiration
it can be categorized as a biochemical
process because the oxidation of food
occurs to various steps to release the
energy
it is the chemical process or chemical
reaction which is taking prints taking
place inside a living organism so it is
called as a biochemical trust the second
major two friends that can be cited
between breathing and cellular
respiration is that in breathing no
energy is reduced
but in case of cellular respiration
energy is released are liberated which
is stored in the form of ATP
although the amount of energy released
is different in the aerobic and
anaerobic person since breathing is a
physical process so no enzymes are in
what
whereas the cellular respiration
requires a lot more idea of enzymes
since it is a multi-step biochemical
process
I hope you all must be knowing what the
enzymes are or what they do enzymes are
the biological catalysts which increase
the rate of reaction the next are the
large difference between breathing and
cellular respiration is that the
breathing is a carbon system-level
process
organ system means in which the organs
are involved for example in case of
human beings the organ in word in the
breathing process is their lungs whereas
in case of plants the organs involved in
breathing process are either stem rooms
or the leaves so it can be done turn
that the organ system level process
because it occurs as the organ level
whereas these cellular respiration since
it takes place inside the scent is the
cellular level process
or in other words it can be also said
that the cellular respiration is a
intracellular process whereas breathing
is a extracellular presence after this
brief discussion in the next part we
will be discussing about the respiration
implants and then finally the
respiration in human beings thank you
very much
