Question
Chapter 17.4, Problem 3CC
Summary Introduction
To explain: How the polypeptide being secreted reaches the endomembrane system.
Concept introduction:
The proteins which are to be secreted are synthesized on ribosomes and bound to rough endoplasmic reticulum. These proteins reach the endomembrane system and are transported in transport vesicles from Golgi apparatus to the outer part of the cell. The endomembrane system is a group of organelles and membranes and the system includes the nuclear envelope, endoplasmic reticulum, and golgi apparatus. They work simultaneously to manufacture and transport proteins and lipids.
