Simple diffusion
Osmosis
Which of the following best describes facilitated diffusion?
*
Movement of molecules through a membrane protein without energy input
Movement of water across a membrane
Transport of large particles into the cell
Movement of ions against their concentration gradient
What is the main difference between active and passive transport?
*
Active transport requires energy; passive transport does not
Passive transport moves molecules up their concentration gradient
Active transport only occurs in plant cells
Passive transport uses carrier proteins exclusively
