All right, to answer this question, i have drawn a plasma membrane, and this plasma membrane is made of a phospholipid bilayer.
00:08
There's two layers of phospholipids.
00:11
And these phospholipids have a hydrophilic head, and so hydrophilic means that it likes water.
00:18
And then the middle section is hydrophobic, which means that it doesn't like water.
00:25
And so if we think about our classes of hormones, we can figure out which one.
00:30
Is able to pass through this membrane without needing a transporter.
00:36
And if it's able to pass straight through the membrane, that is called diffusion because it doesn't need anything to carry it through.
00:44
So let's look at these.
00:47
So an amino acid derived hormone and a peptide hormone and the glycoprotein hormones are all water soluble, which means, they are lipid insoluble...
