And chemical signaling which of the following is considered...

Transcript

00:01 So, the question here is regarding signal transduction, all right? and they have asked that in signal transduction, which among the following option, act as a secondary messenger.

00:14 So before i answer, let us understand what is the signal transduction process.

00:18 So from the name itself, it is pretty clear that it is a process that helps in transferring signal across the cell of an organism.

00:28 So that it can the organism can have a response a specific response to its environment or a stimuli now signal transduction has a variety of components okay on which it rely so the first we have is the receptor okay what are receptors these are protein which we found in the plasma membrane okay and they wait for a signal now these signal which might be of chemical nature okay so these are the signal which might be of a chemical nature these are known as the ligand or you can say it as the first messenger okay so what happens is that these ligand binds with this receptor and then it leads to this signaling process okay now let us understand by diagram so say this is the plasma membrane we have okay this is a plasma and here we have the receptor this is the receptor r and here we have the ligand this is l ligand so this will mine to the receptor ligand okay so this is the first it is acting as the first messenger cause this is what is starting off or kicking off the signaling casket and this will create a reaction inside the cell as a result the signaling process will start and the cell will create a particular response okay now this receptors okay they are very specific because the specific receptor okay they will bind with specific ligand or you can say specific first messenger okay and hence it will create a specific response to a specific stinuli okay although the cell is receiving a lot of signaling but the specific receptor will only bind with the specific ligand itself okay so that a specific response is created all right now what happens is we see in certain receptors okay they after getting after binding with this protein ligand okay they activate other molecule okay and these are known as the secondary messenger i'm writing it as second here.

02:59 So this is i can write it in alphabet.

03:02 So this is secondary messenger...
