hypotonic
isotonic
Passive Transport means
Energy is used
No energy is used
Energy is created
Which type of passive transport uses proteins to help molecules pass through the membrane?
An example of facilitated diffusion is
CO2 and O2 exchange in the lungs
Glucose transport
Na+ / K+ Pumps
Endocytosis
What is this structure?
cell membrane
plasma membrane
vesicle
vacuole
This picture is a representation of what type of transport?
Osmosis because it is diffusing through a protein from an area of high concentration to low concentration.
Facilitated diffusion because it is diffusing through a protein from an area of high concentration to low concentration.
Facilitated diffusion because it is diffusing through a protein from an area of low concentration to high concentration.
Simple diffusion because it is diffusing through a protein from an area of high concentration to low concentration.
