00:01 See the question is asking us regarding integral protein okay integral protein or intrinsic protein both are same, both are same thing okay intrinsic protein now what are they? they are embedded into the plasma layer okay into the plasma membrane in the plasma membrane okay, so let us assume that this is a lipid bilayer, lipid bilayer is basically a plasma membrane right so like this okay, now this is one layer and let us draw another layer of lipid hmm this is the hydrophilic regions which are facing the aqueous environment okay, so lipid bilayer one layer of lipid another layer of lipid right now intrinsic protein is something like this okay, it can it can be present or cover the entire layer of the of the bilayer or it can be present somewhere in between like this okay, this is also an intrinsic protein however if the protein is placed like this so it cannot be called as intrinsic protein but this this this these all are intrinsic protein right now what happen is what is going to happen is they are they are saying that the options is hydro amphiphytic amphiphytic now what is amphiphytic? amphiphytic is that the protein okay? let us say this protein this protein is interacting with the hydrophilic region as well as the hydrophobic region okay? so this is called as amphiphytic like both regions are present hydrophilic as well as the hydrophobic region apart from that what we must focus on that integral protein can be located like this also right so they are hydrophilic also, and they should be hydrophobic as well, but we should also mention about the hydrophobic region now why hydrophobic see if a protein has a hydrophobic region then only it can interact with the tails and be embedded into the plasma membrane like this okay? so option a which says amphiphytic plus hydrophobic is our right answer okay? hydrophobic why hydrophobic because it allows it to be embedded into the into in between or i say in between the bilipid layer okay otherwise if this wasn't mentioned let us say we instead of this we would have mentioned hydrophilic then what would happen then? only if only hydrophilic region is there in a protein so then it must be placed it can be placed like this so then it will be called as extrinsic right so this is why we can't write hydrophilic here...
