Define Active Transport (need to mention the concentration gradient):
When molecules move from a LOW to a HIGH concentration, they are said to move AGAINST their concentration gradient.
ATP (energy) is required.
Above identify the types of transports:
13
Multiple Choice
Which one is the definition of active transport?
movement of particles through the cell membrane from a region of lower concentration to a region of higher concentration using energy in the form of ATP.
passage of water molecules from a region of their higher concentration to a region of their lower concentration through a partially permeable membrane
net movement of molecule from a region of higher concentration to region of lower concentration. Molecule down a concentration gradient
net movement of molecule from a region of lower concentration to region of higher concentration. Molecule down a concentration gradient

PROTEIN PUMPS:
SODIUM POTASSIUM PUMP
Proteins in the cell membrane that require energy in the form of ATP to pump things against their concentration gradient.
The protein changes shape (protein phosphorylation).

ACTIVE TRANSPORT- BULK
ENDOCYTOSIS (two types)
PHAGOCYTOSIS: (CELL EATING)
Large particles, whole cells or solid enter the cell
Enter as a food VACUOLE

ACTIVE TRANSPORT- BULK
ENDOCYTOSIS (two types)
2. PINOCYTOSIS: (CELL DRINKING)
BULK TRANSPORT of dissolved solutes or fluids into the cell
Enter as a Vesicle
Note both are going into the cell
