Cell Transport and Osmosis

Front

Two types of cell transport

Back

Passive and Active

Front

Two types of passive transport:

Back

simple diffusion and facilitated diffusion

Front

When smaller molecules such as oxygen and carbon dioxide can move in and out of a cell across the phospholipid bilayer, this is called:

active transport

,

facilitated diffusion

,

osmosis

,

simple diffusion

Back

simple diffusion

Water can move across the cell membrane through the phospholipid bilayer, and also through protein channels called ____________________.

Back

aquaporins

Endocytosis and exocytosis are examples of:

Back

active transport

Front

Why are protein pumps like the sodium potassium pump considered active transport?

Back

ATP

Front

Endocytosis and exocytosis involve the use of _____________________ to move materials in and out of the cell.

Back

vesicles

ATP stands for...

Back

adenosine triphosphate

Osmosis

Back

diffusion of water across a semipermeable membrane
