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 um [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 of 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 to 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
