Review Week 2
What do selectively permeable membranes allow for?
the formation of concentration gradients
Define passive transport.
the net movement of molecules from high to low concentration
What is the difference between diffusion and facilitated diffusion?
facilitated diffusion uses transport proteins
diffusion uses transport proteins)
True or false: facilitated diffusion allows for hydrophobic molecules and ions to pass through membranes.
What does active transport require?
What is the difference between endocytosis and exocytosis
Endocytosis moves molecules large molecules into the cell, while exocytosis moves them out of the cell
the total solute concentrtaion in a solution
the partial solute concentration in a solutio)
