2.Draw the membranes described in a-c below. You can draw a general phospholipid bilayer representing the phospholipids but be sure to indicate the differences in saturation of the fatty acids if needed. Then include the required proteins and indicate how the molecular transport is happening. Finally, to the side of each membrane, draw at least 1 accurate representation of the specific phospholipids for each membrane and how they would interact (pack together). You will likely need to apply knowledge from General Biology and/or look some things up to complete the work.
