Hello, so today the question that is given to us talking about the different statements and that we need to pick the correct option.
00:08
So the first statement is about the glyphalysis where we know that glypolis is nothing but the conversion of glucose, which has six carbon one to pyruid, which is a three carbon.
00:19
And here it says that it is anabolic path.
00:22
We need to answer whether this statement is correct or not, whether it's anabolic pathway or not.
00:29
So for this, we can simply write that the given statement is false.
00:35
It is false.
00:36
And the correct reason will be that here, it is not anabolic path, but it is actually a cantabolic path.
00:42
Because here, the glucose, which is a six carbon molecule, is breaking down to form to three carbon molecules.
00:49
It is a pyramid.
00:50
And the case of anabolic pathway, we are forming something.
00:52
Some biomolecule is going to be formed.
00:55
Not something is breaking, like in the case of glypolis, that the glucose is breaking.
00:59
That is why this statement is false coming to the second statement that is talking about the chemotaxis what is chemotaxis it is nothing but the movement due to chemicals movement due to chemicals which can be organic and the inorganic bias now how these movements basically what kind of metabolism are going to be supporting such movement so for that we can simply write the aerobic respiration.
01:31
It is the best kind of what you can say metabolism or what you can say reactions that basically involve different kinds of chemicals which basically useful for such organisms that form the chemo taxes.
01:46
Coming to the third statement which is basically that if you compare a sacromyces cerevacy, if you compare sacromysis cerevacy and if you compare stifilopopoporpe.
02:00
Stifilo, cocus, oriors.
02:03
We need to basically answer that if you compare both of them, which one would have the higher s by v volume ratio.
02:11
Basically, you're talking about s by v ratio, which is surface area to volume ratio.
02:17
So about this, we can write that it is actually the estephylo caucus, scephylokocus, orions.
02:27
And why is it so? what is the exact reason here? see when you talk about a secondomyces cerevacy it is nothing but the east which is a eukaryotic and here it is back that is stifiloccus porias now we know that east are obviously much more bigger than the bacterial cell no bacteria is a prokaryote and east is a ucareer but what happened is the smaller the cell the larger the surface area that is the normal logic that we use so here again if we have the smaller surface area we have the comparatively more volume that we will see in the east but if you have a small or what you can say large surface you should have smaller volume that is why we use this s by my rate ratio that is why it's the phylococcus or yes which is basically a bacterial cell will be the correct option coming to the fourth option that is metabolic pathway you are talking about metabolic pathways and here it says that when you talk about different metabolic pathways are these a predictable linear set of reactions in the cyclone of the cell.
03:33
We need to answer whether are these linear set of reactions or no.
03:39
So about this also, like we need to answer whether it is true and false.
03:42
So it is false.
03:43
It is not linear or predictable set of reactions.
03:47
It is complex reactions where multiple reactions are occurring together.
03:55
It is not a single reaction that is performing at once.
03:58
No, multiple reactions are happening together and that is why we say that this statement is false.
04:03
Coming to the next option that is, in order to produce three pyruids in glycolysis, what is the minimum number of glucose molecules needed? so here we know that glucose is there and it will eventually lead to the formation of pyre...
