What is the last step of exocytosis at right?

The last step of exocytosis involves the fusion of the vesicle membrane with the plasma membrane of the cell. This fusion allows the contents of the vesicle to be released into the extracellular space. After the release, the vesicle membrane becomes part of the cell membrane, completing the process. This mechanism is crucial for various cellular functions, including neurotransmitter release and hormone secretion.
