okay so we have the last part of our

cellular respiration

we have oxidative phosphorylation or our

electron transport

chain so that's this will be the last

step for us guys

so no need for that so

first why do we need oxygen

organisms we need oxygen in order to

live so as we all know that

if we hold our breath what could happen

is that

capacitor now we could get dizzy and

then block out or even cause

death capac

oxygen nothing okay but have you ever

wondered

why that's the case or what exactly your

body does with

all that oxygen so we just all know now

what what do they do it's adding oxygen

okay so the reason behind as it turns

out you need oxygen so your cells can

use this molecule during

oxidative phosphorylation or the final

stage of cellular respiration

so hindi sha immediately nega gamete

during glycolysis pyruvate oxidation and

then the krebs cycle

actually oxygen is being used during the

third

and final step of our cellular

respiration

so oxidative phosphorylation is made up

of two closely connected

components that's why i'm at the last

inter interchangeable language

components nato the first one is our

electron transport chain and the other

one is chemi

osmosis so oxidation or oxidative

this phosphorylation net then union

electron transport chain and then

chemiosmosis that would be your

phospho relation okay so you

pass through now adding manga electrons

from one molecule to another your new

electron transport chain

and then for chemiosmosis is the

formation

of our atp

okay because of a certain radiant

ion so where does oxygen fit into this

picture so

oxygen sits at the end of the electron

transport chain

hosa and it accepts the electron and

picks up protons to form

water so yunyung is adding

[Music]

glucose okay and it will pick up protons

oxygen it will pick up protons in order

to form

water molecules so oxygen

electrons the electron transport chain

will stop running

molecules and atp will no longer be

produced by

chemiosmosis because young atp they

never

produce lungs because of the gradient

but since

electrons proceed past the next

step hydrogen ions from one

uh from the matrix upon the center

membrane space

okay so without enough atp in return

cells cannot carry out their actions

that they need to

function okay so that could lead to the

death of

an organism

in the function eventually our body

could die

okay so let's proceed with our electron

transport chain first

so electron transport sheet nothing is

made

involving four large complexes

labeled as one two four one two three

four

and so in eukaryotes many copies of

these molecules are found in the inner

mitochondrial membrane catalytic

cohanina and then of course

the prokaryotes snattin they are just

found in the plasma membranes uh

cell membrane lung nila meron capoxa

prokaryotes pero pogba things are

eukaryotes

it's happening in the mitochondria

specifically in the

crystal or in the inter membrane at the

inner membrane inner membrane i should

say

okay so eternal complex one complex two

complex three and

complex four so ethernet inter membrane

okay so from the diagram

all of the electrons that enter the

transport chain come from nadh and fadh2

otranga

so nadh from glycolysis pyruvate

oxidation and

krebs cycle nfdh to falling language

cycle so what happens during etc

so in the matrix you nadh then above

during the citric acid cycle pyruvate

oxidation

glycolysis and ion

i but the deposit on electrons is a

complex number one

at once among the positioning electrons

are complex number one malamang

and hydrogen ion

plus and it's going to release a proton

into the

matrix okay so fat h2 on the other hand

deposits electrons in complex two okay

turning it into fat and releases two

hydrogen ions

i remember guys an nadh muggy start k

complex one might deliver

so fadh2 complex two language start mic

delivering

electrons

okay so the electrons from complexes one

into our pass to the small mobile

carrier queue

so once in a pass and as a complex one

complex two image electrons

mobile carrier and then carrier q

transports the electrons to

complex three pascal pascal at electron

transport chain

which then after complex three it passes

to cytochrome

c and lastly cytochrome c passes the

electrons to complex

four which density complex foreign

electrons

it will form water remember that

it takes two electrons

okay oxygen and an oxygen molecule and

two hydrogen ions to form one water

molecule so complex is one

three and four use energy release as

electrons move from a higher

to allow energy to pump protons out of

the matrix and into the inter membrane

space so italian makaharo nanometallina

proton

gradients

because its electrons are higher in

energy

level so as electrons move through

complex one in a series of redox

reactions

the complex uses this energy to pump

protons

from the matrix upon the inter membrane

space on the other hand fadh2 have a

lower energy level that's why

hindi nagi starts a complex one it

starts with complex two which does not

pump

protons across the membrane

okay because of this bypass each fadh2

molecule causes

fewer protons to be pumped and

contributes less to the proton

gradient than an nadh

so overall what does the electron

transport chain do for the cell it has

two

important fraction functions number one

is to regenerate the electron carriers

so we have nadh and fadh2 magiking

any d plus and fed

okay number and next this is important

because the oxidized forms oxidability

oxidized forms

ition ah sorry sorry nad plus nfed

big sabihin they have lost an electron

forms of these electron carriers are

used in glycolysis and the citric acid

cycles

glycolysis anticitric acid cycles

and number two it makes a proton

gradient gusto nothing new

formula protein gradient because

name process than chemiosmosis so when

you say chemiosmosis

this is the process in which energy from

a protein gradient is used

to make atp proton gradient

so ingredient is union chemi in a part

and then osmosis is

moving from one moving through i

membrane and form of course a certain

energy which is in the form of

atp okay so for instance chemiosmosis is

also involved in the light reaction of

photosynthesis

so complex one three and four of the

electron transport chain our

chain are proton pumps so as electrons

move energetically downhill

the complexes capture the release energy

and uses to pump

your hydrogen ion statin from the matrix

to the inner

membrane space

so an electrochemical gradient across

the inner mitochondrial

membrane where in antarctic

gradient nato is a proton motive

force okay

instead after being turned by water

hydrogen ions

okay and in turn you atp synthase and

gagawinia

it is going to add a phosphate group the

one guy adp

through the protein gradient into the

form e t

p so basically get into your area guys

so what happens is after presenting

citric acid cycle nitin

submarine diet nadh gonna produce at

fadh tena produce so nadh will

give off its electron at once on the gif

electron ion pumping hydrogen ions from

the matrix papuantesa

inter membrane space so nadh will become

nad plus and hydrogen ion

and then simultaneously afad h2

will deliver its electrons k complex two

but since the complex two a hindi

hydrogen ions from the matrix from the

inter membrane space

and then pass a high cytochrome c and c

will pass it to four and then four

pop-up nanometer hydrogen ions and the

new electrons and nandito i4

will give off will give of its electrons

our oxygen and that elect

electrons will again magnesium oxygen

will attract two hydrogen ions forming

water molecules

electrochemical gradient detox inter

membrane space

meaning there is a high concentration of

hydrogen ions due to the inter membrane

space that in and what will happen

is proton motive force and that proton

motive force

will drive this atp synthase

to add a phosphate group

chi adp to form atp

okay so generally that is what is

happening

in the electron transport chain

and then chemi osmosis so all in all

antarctica is oxidative phosphorylation

okay oxidative because of the continuous

losing of electrons here and then

lithium ion is phosphorylation with the

formation of

our atp

okay so sinatra

alexa citric acid cycle and sugglycola

subglycolysis paramagame

so that's it for our electron transport

chain
