Is not a target protein in signal transduction.
00:06
Proteins that regulate gene activity.
00:09
Hormones that activate the receptor.
00:12
C, enzymes of pathways.
00:15
D, transport proteins.
00:17
Or e, the enzymes of cell reactions.
00:21
Okay, so what this question wants you to do is to split the signal transduction process, not into the three parts, reception, transduction, response.
00:31
But into a very simple reaction.
00:34
There is a signaling molecule, and there is a receptor.
00:43
And they bind.
00:44
Maybe the receptor is on the surface of the cell...
