Practitioners of naturopathic medicine often use “essential oils” such as lavender oil. (Note that essential refers to their essence or scent and does not imply that these substances are necessary for health.) One of the components of lavender oil is shown below. Based on its structure, could this molecule diffuse through the cell membrane of a skin cell after the oil was applied to the skin surface?
An artificial cell consisting of an aqueous solution enclosed in a selectively permeable membrane (but with no cell wall) is immersed in a beaker containing an aqueous solution. The outside environment concentration consists of 0.01 M glucose and the inside of the cell has a concentration of 5.0 M glucose. The plasma membrane is permeable to water and monosaccharides, but impermeable to the disaccharides. Complete the following for the image below:
Will the artificial cell become lyse, shrivel, or stay the same?
lyse
shrivel
