Summary Introduction

To encircle:

A patch of plasma membrane that is coming from a vesicle involved in exocytosis.

Concept introduction:

Exocytosis is the process by which the macromolecules synthesized in the cell is transported outside the cell.

In this process, the substances synthesized in the endoplasmic reticulum are packaged in the Golgi apparatus and then transported through transport vesicle to fuse with the plasma membrane. The fusion of vesicles with the membrane spills the substances outside the cell.
