Part C - Facilitated diffusion via channels and carrier proteins The majority of solutes that diffuse across the plasma membrane cannot move directly through the lipid bilayer. The passive movement of such solutes (down their concentration gradients without the input of cellular energy) requires the presence of specific transport proteins, either channels or carrier proteins. Diffusion through a transport protein in the plasma membrane is called facilitated diffusion. outside cell channel protein inside cell carrier protein' Adapted from Biology by Campbell and Reece ©2008 Pearson Education, Inc. Sort the phrases into the appropriate bins depending on whether they are true only for channels, true only for carrier proteins, or true for both channels and carriers. ▸ View Available Hint(s) only channels transport primarily small polar organic molecules provide a continuous path across the membrane provide a hydrophilic path across the membrane allow water molecules and small ions to flow…
Draw out protein transport in the cell. Make sure to include all steps involved in transport through the secretory and endocytic pathways (including ER resident protein retrieval, transport to lysosome), transport in and out of the nucleus, and import into mitochondria.
