1
Active Transport A type of cellular transport that requires energy to move material across the cell membrane. This is going to show how cells transport substances in and out. 1
2
Key Points of Active Transport
The Plasma Membrane 1/12/2019 Key Points of Active Transport Moves materials from LOW to HIGH concentration AGAINST the concentration gradient Requires energy or ATP G. Podgorski, Biol. 1010 2
3
What does it mean to move materials from low concentration to high concentration?
4
What does AGAINST the concentration gradient mean?
B To get this result A B We need ENERGY Naturally, the liquid from A will move towards B until equilibrium is reached. What if I needed the materials from B to move into A (against the gradient)? What would be necessary to accomplish this?
5
How does ATP provide energy?
ATP= Adenosine TriPhosphate When the bond between phosphates is broken, energy is released!
