● _________________ allows molecules to move
across cell membranes and epithelial
membranes against a concentration
gradient.
● This movement requires energy
(adenosine triphosphate [ATP]) and a
carrier mechanism to maintain a higher
concentration of a substance on one side
of the membrane than on the other.
● Concentration Gradient – Inequality of
concentration in solutes between the two
compartments hence concentration
gradient is created.
● Complex sugar, ions large cells, proteins,
and other particles are transported in this
process.

WHAT ARE THE TWO TYPES OF ACTIVE TRANSPORT
1. Primary Active Transport:
● uses the initial source of energy to
carry the substance
2. Secondary Active Transport
(cotransport)
● harnesses the energy obtained
from the primary active transport
and uses it as a cotransporter of a
secondary substance

secondary substance
Secondary Active Transport
(cotransport)
75
WHAT ARE THE EXAMPLES OF PRIMARY ACTIVE TRANSPORT?
1. SODIUM POTASSIUM PUM
2. ENDOCYTOSIS
3. ENDOCYTOSIS
76
a plasma membrane surrounds the
substance being transported and
transports the substance into the cell.
ENDOCYTOSIS
77
WHAT ARE THE THREE (3) MAIN KINDS OF ENDOCYTOSIS
a. Phagocytosis or cellular eating
b. Pinocytosis or cellular drinking
c. Receptor-Mediated Endocytosis (RME)
78
Occurs when the dissolved materials enter
the cell. The plasma membrane engulfs
the solid material, forming a phagocytic
vesicle. (There is fluid inside)
Phagocytosis or cellular eating
79
Occurs when the plasma membrane folds inward to form a channel allowing dissolved substances to enter the cell. When the channel is closed, the liquid is
encircled within a pinocytic vesicle.
Pinocytosis or cellular drinking
80
Also called clathrin-mediated endocytosis, is a process by which cells absorb metabolites, hormones, proteins – and in some cases viruses – by the inward budding of the plasma membrane
c. Receptor-Mediated Endocytosis (RME)
81
1. Moves materials out of the cell
2. Materials is carried in a membranous
vesicle
3. Vesicle migrates to the plasma membrane
4. Vesicle combines with the plasma
membrane
5. Materials is emptied to the outside
ENDOCYTOSIS
82
differentiate the difference of EXOCYTOSIS and ENDOCYTOSIS
Endocytosisis inside it will be carried onto the
vesicle, the vesicle will be formed and the
materials will be transported inside the cell.
Exocytosis whatever the materials will be
released on the outside, inside the cell will also
be covered inside the vesicle it will attach itself in
the plasma membrane releasing now the
materials or the molecules
83
________________ inside it will be carried onto the
vesicle, the vesicle will be formed and the
materials will be transported inside the cell.
Endocytosisis
84
_____________ whatever the materials will be
released on the outside, inside the cell will also
be covered inside the vesicle it will attach itself in the plasma membrane releasing now the
materials or the molecules
Exocytosis
85
In this biological process, there is no need
for any energy for transporting the
molecules, as the biochemicals move
from higher to lower concentration. This
process is carried out to maintain the
balance and the equilibrium level in a cell.
All the waste molecules including water
and carbon dioxide are separated and
moved out of the cell using passive
transport.
PASSIVE TRANSPORT
86
● __________________is the process by which water
moves across a selectively permeable
membrane from an area of lower solute
concentration to an area of higher
solute concentration.
● A selectively permeable membrane
allows water molecules to cross but is
relatively impermeable to dissolved
substances (solutes). Osmosis continues
until the solute concentration on both
sides of the membrane is equal.
