So on a diagram, it shows you the three parts of signaling transaction pathway.
00:05
So the question asks you to list step one, two, and three.
00:09
So step one is right here.
00:15
Basically is where the signal molecule bind to the receptor.
00:19
And we call this step reception.
00:27
Step number two is this pathway right here, from the circle molecule to the rest of other molecule.
00:34
Step number two, we call this transduction.
00:38
So signal is being transduced into the next enzyme in line.
00:46
And the step number three is eventually the transduction hit the final step, the activation of cellular response.
00:56
And so we call this step response.
01:05
Now, the next question, there are several abcd4.
01:10
Options, match the type of signaling molecule or the ligand with the appropriate receptor.
01:19
The first one is insulin.
01:24
Insulin signal molecule is going to combine to the insulin receptor.
01:33
Insulin receptor is a protein kinase receptor.
01:46
So basically the signal is passing to the receptor and then there is a lot of relay molecule and every single one is a kinase to pass along.
01:57
The signal to the response, which is the glute four transporter...
