Hello students and the first question which is question number 15 we have to tell the functions of phospholipids and the cell membrane so the phospholipids they are the important component of cell membrane and the functions of phospholipids are in the cell membrane the phospholipid cluster together to form lipid which forms a barrier around the cell.
01:08
And thus the interior of the cell is separated from the outer environment.
01:14
And the same function of phospholipid cells.
01:17
Because of the nature of the phospholipid, the cell membrane maintains the selective permeability and the phospholipid tail, it makes the lipid bilayer pythorbid.
01:46
That only the small or uncharged molecules can pass.
01:52
Now the phospholipid maintains, third is the fluidity of the membrane.
02:02
It is maintained by phospholipids.
02:10
The fatty acid composition of the fatty acid, or sorry, phospholipids, they are important factor, which describes the fluidity of the membrane.
02:20
Now for the question number 16 we have to tell the phospholipids are amphipathic so what does this mean? so answer for the question number 15 that phospholipids are amphipathic.
02:39
This means they have both polar and non -polar quotients.
02:50
This is the meaning of term amphipathic and the structure of phospholipid consists of polar head and which is hydrophilic and non -polar hydrocarbon chain which are hydrophobic hydrophilic head and hydrophobic tail so because the amphipathingature phospholipids form the bilayer structure with the hydrophobic head lies outside and interact with the equest environment where is the hydrophobic tail it clusters inside.
03:57
Now for the question number 17 we have to label the given diagram.
04:03
So for this, this portion is polar which is head and this is the both are non -polar which is tail.
04:22
The important components of phospholipids head is phosphate growth.
04:34
Which is negative and polar...
