Passive transport
Fill in the blanks
Passive transport moves molecules from areas of *blank* to *blank* concentration
Passive transport moves molecules from areas of high to low concentration using no energy
True or False
Exocytosis is an example of a passive transport
False
Exocytosis is an example of an active transport due to the energy being used
