The Golgi complex is especially active in processing proteins for secretion.
Many of these are synthesized with an N-terminal signal peptide that targets them for secretion.
This is the result expected if the signal peptide were necessary for secretion.
Thus, the expected time for intestinal secretion was limited.
It is a deep infolding, or little channel, which serves to increase the surface area, e.g. for secretion.
The rhopteries appear to have subcompartments allowing for differential secretion during the life cycle.
These extensions increase the surface area of the cell allowing for greater absorption and secretion.
The main stimulus for secretion of vasopressin is increased osmolality of plasma.
They use both apocrine and merocrine methods for secretion.
The apical plasma membrane projects microvilli to increase surface area for secretion.
