Hello everyone.
00:02
So, according to the question, we need to find the function of the bacteria that is present in our large intestine.
00:08
And there are options given in the question.
00:11
So, between those six options, we need to find the correct one, right? so, let us discuss one by one.
00:18
So first we will see the roles of bacteria present in our large intestine.
00:25
We can call them as gut bacteria, right? so, what is the role of this gut bacteria? we will discuss that one by one.
00:36
So first of all, these bacteria, they have different protective, metabolic and trophic functions, right? so, they serve as the central line of resistance.
00:53
Central line of resistance for what? resistance to colonization by the to colonization by exogenous microbes.
01:08
Okay, so basically we can say that the gut bacteria protect our intestine from some microbes or pathogen.
01:16
So basically the gut bacteria prevents, okay, they will prevent the invasion of our intestine mucosa, okay, intestinal, mucosa by the pathogen, okay? mucosa by pathogen.
01:34
So, this is the protective function of gut bacteria.
01:37
And this effect here that we described, it is called as barrier effect, okay? it is called as barrier effect and it also has another name or we can say this as colonization resistance, okay? colonization resistance resistance so if you will see the question the first option is given us the second option is given us protection from colonization by the pathogen which is correct according to what we discussed now now we will see what are the other function that gut bacteria can perform so here comes the second point that the gut bacteria the gut bacteria has impot and in the supply of essential nutrient.
02:25
So basically it involves or it helps in the supply of some essential nutrient that is it provides vitamin k.
02:39
Okay? vitamin k we can take that as example.
02:43
Now if we will see another function or we discuss the another point...
