Question
Chapter 4.5, Problem 6MC
Summary Introduction
To determine:
The way in which exocytosis and endocytosis use vesicles to transport materials across cell membranes.
Concept introduction:
The exocytosis is the process in which a vesicle which delivers substances to the cell membrane. This vesicle then attaches or gets fused with the membrane and then it releases its material or cargo to the outside of the cell. Endocytosis is the process in which cell surrounds and intakes liquid or big particles inside itself.

Select all that apply.
A) Involves transport vesicles
B) May be used to move a hydrophilic substance to the other side of the membrane
C) Requires energy
D) Always moves a substance down its concentration gradient
E) Always results in a substance exiting from the cell
.
Which type of endocytosis involves the binding of specific substancesin the extracellular fluid to membrane proteins? What does this type oftransport enable a cell to do?
