Hello, so let's answer now the question.
00:02
So we have four structures of proteins.
00:08
We have the primary, secondary, tertiary, and quaternary.
00:12
But here in the up in the question, it is up to only tertiary structure.
00:18
So let's start with the first statement about the tertiary structure.
00:24
So letter a states that tertiary structure, three -dimensional structure stabilized by disulfide bonding, this statement is correct.
00:34
Take note that we are, by the way, looking for the mismatched in terms of the structural level and the definition or description.
00:47
So tertiary structure is the three -dimensional shape of a protein, so it's correct.
00:54
The tertiary structure will have a single polypeptide chain or backbone with one or more protein secondary structures.
01:01
The protein domains amino acid side chains may interact and bond in a number of ways so again the point here is tertiary structure contains 3d structure next let's go for option b option b states that secondary structure hydrogen bonding is most important bonding this statement is true because of the hydrogen bonding the secondary structure can have the alpha helix shape and then the beta pleated sheet shape and primarily it's because of hydrogen bonding so this statement is okay so we have here option c it states that tertiary both alpha helis and beta sheets can participate for the three -dimensional structure so this statement is true.
02:11
Okay.
02:12
So in tertiary, the alpha helices and the beta sheets will also contribute to the 3d dimension of the 3d dimension of the protein.
02:27
So it's correct...
