Okay, i'm not to answer this question as states if the following terms are true or false.
00:05
So first, for example, we have this statement here that says stereophormones don't use a second messenger.
00:10
And this is true.
00:12
Remember that the steroformants are lipids soluble molecules.
00:16
It means in the cell membrane, they are going to be able to cross a cell membrane directly because the core of the cell membrane is made of lipids.
00:24
And stereos hormones are made of liquids.
00:26
So, steroids hormones are going to be able to cross the cell membrane directly.
00:29
And they are going to mine to the receptor that is inside of the cell.
00:33
And these receptors inside of a cell are not going to require second mesencers.
00:36
So the second messengers are used by receptors that are present on the surface of a cell membrane.
00:43
Then we have the second messenger system, apply the signal generated by a hormone.
00:49
And this is also true.
00:50
Okay, this is one characteristic of second messengers.
00:53
Then we have here cyclic amp and calcium ions are example of second messengers...
