What is the primary difference between regular active transport and passive transport?
Question 2
2.
What molecules are used to fuel the process of active transport?
Question 3
3.
Sort the following
Moves molecules against the concentration
Involves the use of a protein pump
Involves the movement of solutes from areas of high concentration to areas of low concentration
Involves solutes moving through a protein channel without the use of energy
The goal is to reach dynamic equilibrium
Involves the movement of water
Does not require energy
Involves the movement of solutes from areas of low concentration to areas of high concentration
Simple diffusion
Facilitated diffusion
Osmosis
"Regular" active transport
