Transport Through Membranes Passive Transport- does not expend energy Active Transport- cell supplies energy Diffusion- tendency for molecules to spread out into availability. Net movement down concentration gradient Osmosis- type of diffusion Solvent- substance capable of dissolving Solute- dissolved substance Isotonic- 2 solutions have same solute concentration Hypertonic- higher concentration of solute lower concen Hypotonic- lower concentration of solute higher concen Carrier mediated transport- utilize transport protein, allows molecules to avoid contact with lipid bilayer and cross

Unformatted text preview: over Facilitated Diffusion- requires concentration gradient, solute binds to transport protein, protein changes shape and opens channel through membrane Large Molecules • Exocytosis- cell ejects waste products or secretory products by having a vesicle fuse with plasma membrane • Endocytosis- material taken into the cell by vesicles Phagocytosis- folds of membrane enclose particle and form vesicles which pinches off into cell, vacuoles fuses with lysosomes that digest the content...
