Front 9

Movement of substances across a cell membrane using energy

Back 9

active transport

Front 10

Movement of a substance across a cell membrane without the use of energy, from a region of higher concentration to a region of lower concentration

Back 10

Passive Transport

Front 11

Passive transport by the random diffusion through the cell.

Back 11

Simple Diffusion

Front 12

Passive transport across a cell membrane with the assistance of a protein that changes shape.

Back 12

Facilitated Diffusion

Front 13

Give some examples of Simple diffusion

Back 13

Lipid soluble and small hydrophilic molecules

hydrophobic through the bilayer
Hydrophilic through protein pores

Front 14

Give an example of facilitated diffusion

Back 14

Glucose

down a concentration gradient, but much faster than simple diffusion

Front 15

Explain Active transport

Back 15

energy from ATP is use to change the shape of an integral protein (Na/K) pump.

Front 16

What is the (Na/K pump)

Back 16

simultaneously bringing two K+ ions into the cell and moving 3 Na+ ions out of the cell

Front 17

name this

Back 17
