are studying chapter respiration in
that we are studying topic types of
respiration
when i say types of respiration there
are many aerobic, anaerobic ,facultative
obligate, fermentation let's study and
find out about each one of them.
Respiration when you say the
respiration it is a process in which
glucose is broken down into ATP in the
mitochondrial matrix that's respiration
you want a plant wants to gain energy by
breaking down glucose molecule but there
are different kinds of respiration which
we'll go through today the first one
aerobic respiration and when i say
aerobic respiration
it means respiration that takes place
with the help of oxygen yes oxygen is
completely required in this process it
leads to complete breakdown or oxidation
of organic food materials and along with
that carbon dioxide and water are
produced as a by-product in this type of
reaction the second one that anaerobic
respiration the name itself says in
anaerobic respiration oxygen is not at
all a medium it is a intracellular
process and it can take place even in
the absence of oxygen in mitochondrial
matrix anaerobic respiration takes place
in certain point of time many organisms
do anaerobic respiration just to survive
now anaerobic respiration is further
divided into various step one of them is
fermentation and fermentation could be
two different types one is alcoholic
fermentation and the other one is lactic
acid fermentation when it's in
fermentation it means it is an
extracellular process in which an
organism and most of the time the
organism is Saccharomyces cerevisiae
thus breakdown of organic products to
liberate certain amount of oxygen and
certain amount of co2 now fermentation
for fermentation products could be of
two different types one is alcoholic
fermentation and another one is lactic
acid fermentation
let's talk about alcoholic fermentation
in alcoholic fermentation the by-product
is ethyl alcohol especially during
brewing process and called fermentation
takes place but it's during lactic acid
fermentation the product is lactic acid
there is something called facultative
fermentation or you can say facultative
my
anaerobes and another
obligate anaerobes which they plug-in
aerobic respiration which should be
going through today
types of respiration now in this types
of Transportation we will be studying
amazingly about two types of respiration
the first one is aerobic respiration and
the next part would be anaerobic
respiration now when I say about aerobic
respiration it occurs in the presence of
o2 or oxygen and that leads to complete
oxidation or against a complete
breakdown of substances and the
substances has to be organic substances
like carbohydrates proteins lipids fats
to generate energy in the form of ATP
and liberate co2 and h2o which can be
used in the photosynthesis process that
various kinds of exact organisms that
actually undergo this process of aerobic
respiration one of them is facultative
anaerobes
now when I say facultative anaerobes it
means that they can exist in the
presence or absence of oxygen even if
oxygen is present or absent their work
is never stopped one of them is east of
sacrifices services which does the
process of fermentation of breaking down
of various edible products which are
spongy in nature the next one is
obligate anaerobes now obligate
anaerobes are the ones which cannot
survive or thrive in an environment
where oxygen is present oxygen is linked
to them on oxygen can kill to them so
they cannot survive with oxygen present
in and around s surrounding they need an
absence of oxygen an example of this is
methane bacteria now mutant bacteria is
huge
during biogas production or go by gas
production that is the reason the biogas
do is fully covered and fully packed
with bricks so that no extrusion can get
an entry and methanogenic bacteria can
do their work silently and produce
biogas as a myth him
another illustration will take place in
the absence of oxygen and partial
oxidation or incomplete oxidation of
organic substance happen in this process
now there are different kinds of
anaerobic respiration one of them is
fermentation and when I say fermentation
it is an extra cellular step or you can
say extra cellular process that takes
place outside cell type of anaerobic
respiration that happens in the absence
of oxygen using microbes like sacrum
Isis NAC
or East especially the making or raising
any product uses fermentation as a
product now fermentation could be of two
types one is alcoholic fermentation and
another one is lactic acid fermentation
when I talk about alcoholic fermentation
it uses on the input of ethyl alcohol
then as lactic acid fermentation will
produce lactic acid as an end product
and it is produced by the breakdown of
milk sugar which is lactose students in
this part of the chapter what we didn't
study was about aerobic and anaerobic
respiration what would be the various
parameters of Arobin expedition and what
could be the business parameters of
anaerobic respiration and what are the
types of anaerobic respiration that was
lactic acid and other words I call it I
hope you are very clear about this
concept of types of respiration thank
you
