Hello, so let's answer now the question.
00:02
So our question here is about the hormones, and the hormones that are secreted by the endocrine system can be divided into two.
00:16
It can be a steroid hormone or it can be a peptide hormone.
00:25
So let's fill in the blank to complete the thought of each sentences.
00:30
Okay, so let's start with the first one.
00:33
So again, there are two main types of hormones.
00:37
So the first word here is we have hormones.
00:42
And this can be a peptide hormone or a steroid hormone.
00:46
So these molecules or hormone will bind to the receptors of the surface of the target cells.
00:52
So the next word here is we have receptors.
00:59
Next, after the peptide hormone epinefine binds to the target cell, the next word here is the c -a -m -p for.
01:10
And then activates a protein kinase enzyme within the cell.
01:17
Next, the epinephrine initiates a signaling cascade as the first word on the fourth statement or fourth sentence is we have first messenger.
01:33
Okay, first messenger.
01:39
And on the second one, this first messenger, it binds to an external receptor of the cell.
01:45
So we have external messenger or external receptor rather.
01:55
It binds to the external receptor of the cell...
