in the previous video when we were covering aerobic respiration I told you that the link reaction CP cycle and oxidative phosphorilation together with ch osmosis happens in the mitochondria so we are going to look at the structure of the mitochondrian and explain how these particular characteristics allow the mitochondrian to carry out the process quite efficiently if you remember the mitochondria it has the outer membrane it's a double membrane organal it has a smooth outer membrane and a folded inner membrane and it has its own circular naked DNA um and it also has 70s ribosomes which I've highlighted so let's focus on the circular DNA and 70s ribosomes because it has its own circular DNA and 7s ribosomes they can work together to carry out protein synthesis how is protein synthesis happening well the circular DNA will undergo a process known as known as transcription to produce the MRNA and the MRNA will move towards the 7s ribosomes and undergo translation and it produces the proteins you may be wondering what kind of proteins do the mitochondria need to produce or synthesize and they will usually synthesize enzymes needed in respiration so remember respiration for example the link reaction crap cycle and also oxidative phosphorilation it's not just pre steps there are multiple steps within each of those process and all those steps require their specific enzymes so the mitochondria function is to actually synthesize those enzymes and they can do it by themselves by the way so that's a good thing number two is the Matrix The Matrix is a space where it's the site of Link reaction and crap cycle and the third part which I've highlighted in a pink area here these finger like structures are known as the christe and the chiste are the folded regions of the the inner membrane in biology when something is folded it's usually to increase the surface area but to increase the surface area of what exactly when you have a folded region to form the chiste the mitochondria is able to contain more electron transport chain and ATP synthes because that's where the ETC and ATP synthes are located so when you have more Etc and ATP synth this the mitochondria can carry out more oxidative phosphorilation and chem osmosis then you also have the outer membrane it forms a partially per permeable membrane that only allows specific molecules to enter the mitochondria for example pyro if you remember pyro is produced in glycolysis uh in the cytoplasm and it only allows the pyate to enter across through the outer membrane and then Enter the Matrix all right uh reduce Neds will be able to do so as well if you look here in this inner membrane the cristate or the inner membrane notice I'm drawing out all these weird looking structures now if you look at it in the elect uh electron microscope you will be able to see these kind of weird stocks all right we call it stocks and the scientists will refer to it as something known as stocked particles and the stocked particles are just essentially ATP synthes and as you can see because the inner membrane is folded it has more stocked particles or ATP synthes and logically when you have more ATP Sy syn what happens to you know ATP production obviously it can increase that is why it's quite interesting to note that the more fold your mitochondrian is the more efficient it is in producing or synthesizing ATP that's all we have to know about the adaptation of the mitochondrian by the way there nothing much to actually mention about that
