Exocytosis and Endocytosis

Endocytosis is defined as

• the movement of large molecules from the inside of the cell to the outisde of the cell using channel proteins. 
• the movement of large molecules from the inside of the cell to the outisde of the cell membrane vesciles. 
•  the movement of large molecules from the outside of the cell to the inside of the cell using membrane vesciles.
• the movement of large molecules from the outside of the cell to the inside of the cell using channel proteins. 

Exocytosis is the movement of

• any type of substance from outside the cell to the inside of the cell. 
• very large substances from outside the cell to the inside of the cell. 
• any type of substance from inside the cell to the outside.
• very large substances from inside the cell to the outside.

Active transport _______ and is the movement of a substance from _____ to _____ concentration

• requires energy, high to low
• requires no energy, low to high
•  requires no energy, high to low
•  requires energy, low to high

If something goes down its concentration gradient it goes from

• an area of low concentration to an area of high concentration

• an area of high concentration to an area of low concentration
