In which process does a secretory vesicle fuse with a cell membrane and release its contents into the extracellular space?
Exocytosis
Exocytosis is an energy-consuming process that expels secretory vesicles containing nanoparticles (or other chemicals) out of the cell membranes into the extracellular space. Generally, these membrane-bound vesicles contain soluble proteins, membrane proteins, and lipids to be secreted to the extracellular environment.
Which process is occurring when a vacuole fuses with the cell membrane and releases its contents outside the cell?
exocytosis
During exocytosis a vacuole containing material to be excreated from the cell moves to the plasma membrane and fuses with it. The vacuole membrane becomes part of the plasma membrane and the contents are released to the outside.
What is it called when a vesicle fuses with the cell membrane and then empties its contents into the space outside the cell?
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. The fusion of the vesicles with the plasma membrane is called exocytosis.
Which process will expand the plasma membrane?
Exocytosis and cell mechanics However, this recycling and delivery of membrane by exocytosis can be used by the cell to enlarge the membrane and surface area during cell shape changes.
