There are two substances get into cells:
Passive Transport; does NOT require energy
Active Transport: DOES require energy

7
Types of Passive Transport include
Simple Diffusion
Facilitated Diffusion
Selective Diffsuion
Osmosis
This type of transport moves substances from high concentration to low concentration

Active Transport
Use energy
Moves molecules from low concentration to high concentration
Helps cells keep "stockpiles" of materials
11
Examples of Active Transport Include:
Calcium Pump
Sodium-Potassium Pump
Secondary Active Transport
Endocytosis; Phagocytosis, Pinocytosis
Exocytosis
12
The Calcium Pump:
Helps muscles contract
Keeps high concentrations of Ca in the cell
Uses ATP to change the shape of the transport protein to move the ion
13
The Sodium-Potassium Pump:
Moves Na+ out
Moves K + in
Called an anti-porter
Uses ATP
How your nervous system works
14
Secondary Active Transport
Does NOT use ATP as the energy source
Glucose enters at the same time as sodium
Called a symporter
15
16
Endocytosis:
Cell shifts the cell membrane in order to bring substances INTO the cell
Pinocytosis-cell drinking
Phagocytosis-cell-eating
Uses a lot of energy and is NOT always safe
17
Exocytosis
Cells shift the cell membrane to get rid of substances from the cell
Uses a lot of energy
