Which of these is true about receptor -mediated endocytosis? all of them? none of them.
00:08
C, a ligand binds specifically with a receptor on the extracellular surface of the membrane.
00:14
D, some transport vesicles fuse with a lysosome, breaking down the contents.
00:19
Or e, vesicles transport receptors back to the plasma membrane.
00:23
So, receptor -mediated endocytosis, also called clatterin -mediated, because it involves claffarin, and this is a way of getting bulk material into the cell.
00:34
And the first step does involve receptors on the surface, and a ligand that binds specifically to them.
00:45
So they have to be the correct shape to fit into receptor.
00:48
So c is going to be a true statement.
00:52
When we get that binding, then we get the clatterin forming on the outside, are the inside of the membrane, and we get the invalination of the membrane, like so...
