Facilitated Diffusion - A passive process where specific protein carriers or channels are used, Simple Diffusion - Happens through the phospholipid bilayer and limited to small particles, Co-Transport - Two different particles are transported through the same protein at the same time, Example of Co-Transport - Glucose and Na+, Thinner membrane - Factor that affects the rate of diffusion, Intrinsic protein - Molecules that span the membrane from side to side, Channel Protein - Consists of pores lined with polar groups (Hydrophilic), Carrier Protein - A particular molecule attaches to its binding site  and causes it to change shape/ rotate, Gated Channel - Opens and closes depending on the needs of the cell, Saturated - All protein carriers are in use, Respiratory inhibitor - Doesn't affect passive processes, Diffusion - Radom particle movement, Concentration Movement - High to Low, Simple diffusion is limited to - Non- polar or lipid soluble molecules, Smaller the molecule - More lipid- soluble it is, Membrane Permeability - Increases rate of diffusion. Affected by salt concentration,
