All secretory vesicles forming from the trans Golgi
network (TGN) leave the TGN in a steady stream and are fused with
the plasma membrane as soon as they get there. As a result, the
membrane proteins and the lipids in these vesicles provide new
components for the cell’s plasma membrane, while the soluble
proteins inside the vesicles are secreted to the extracellular
space.
True or False
Cell Suface Receptors have all the following variable
characteristics except which of the following.
Upon subunit dimerization they signal for
autophosphorylation of lysine amino acids.
Ligand binding can inititiate dimerization.
They can allow ions to move through the cell
membrane.
When bound to ligand they couple protein signals for
nucleotide hydolysis.

statement is generally true about the lumen of the endoplasmic
reticulum in a eukaryotic cell?
