Is there any energy expended by the cell in passive transport?
What allows for the passive transport of material?
What is facilitated diffusion?
If substances need to pass through a membrane against the concentration
gradient, what is required and in what form?
6. Besides energy, what else is needed to move a substance against the
concentration gradient?
7. Define active transport (four criteria)
8. How do large particles move into a cell?
