Chapter 4.5, Problem 6MC
Summary Introduction
To determine:
The use of vesicles during exocytosis and endocytosis for the transportation of materials across the cell membrane.
Introduction:
Movement of molecules takes place from inside to outside and vice-versa in the living cells. There are two types of movement, endocytosis, and exocytosis, which are adapted for the movement of molecules across the cell membrane.
