Name:
passive transport:
Facilitated Diffusion
Direction of
movement
(with
concentration
gradient or against
concentration
Gradient)
Requires Energy
(ATP)
Requires
membrane proteins
Types of
membrane proteins
(protein pumps or
protein channels)
Examples:
Specificity (
Transports specific
molecules or any
molecule that is
able can pass)
.
Simple Diffuse
Passive transport:
Direction of movement
(with concentration
gradient / or against
concentration gradient)
Requires Energy (ATP)
Yes/ no
Requires membrane
proteins
Types of membrane
proteins
Examples:
Specificity specific
molecules or any
molecule
Active Transport
Exocytosis
Energy (ATP)
requirement
(yes/ no)
Definition
Formation of a vesicle
(yes/ no)
Examples
Cellular/ biological
importance
Direction of Vesicle
movement
(moves things inside
cell or outside cell)
Endocytosis
Exocytosis/ Secretion of a Protein Activity.
In this activity the following IB Assessment Statement will be addressed
Explain how vesicles are used to transport materials within the cell between the rough
endoplasmic reticulum, Golgi apparatus and plasma membrane
Instructions: Order/ number the following list of 8 events in the correct order. Then
make a drawing that fully explains the below points.
A.
Vesicles fuse with plasma membrane;
B.
Vesicles formed from rER transport proteins to Golgi apparatus;
C.
Contents of vesicles are released to outside of cell via exocytosis;
D.
Vesicles move through cytoplasm;
E.
Transport vesicles bud off and leave Golgi apparatus;
F.
Proteins inside vesicles are processed as they move through Golgi
apparatus
G.
Proteins are synthesized by ribosomes in the Rough Endoplasmic
reticulum
H.
These vesicles fuse with membranes of Golgi apparatus;
Below make an ANNOTATED drawing that fully explains the above points.
In this activity the following IB Assessment Statement will be addressed
Describe the process of endocytosis.
Instructions: Order/ number the following list of 8 events in the correct order. Then
make a drawing that fully explains the below points.
a.
vesicle breaks away from membrane/moves into cytoplasm;
b.
. plasma membrane sinks inwardly/forms pit/invaginates to enclose
target particle;
c.
.inner phospholipid layer of (original) cell membrane becomes outer
phospholipid layer of vesicle membrane; outer phospholipid layer of (original) cell
membrane becomes inner phospholipid layer of vesicle membrane;
d.
.Vesicle membrane seals back on itself / edges fuse;
one membrane layer / two phospholipid layers enclose particle making
vesicle;
Below make an ANNOTATED drawing that fully explains the above points.
