- Is there any receptor (s) on the interior / cytoplasmic side of tha plasma membrane ? If yes , discuss.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?"Tight junctions perform two distinct functions: they seal the space between cells to restrict paracellular flow and they fence off plasma membrane domains to prevent the mixing of apical and basolateral membrane proteins" is true or false.
- cell membrane function (detailed explanation)Neurons have long thin processes called axons, structuresspecialized for conducting signals throughout the organism’s nervous system. Some axonal processes can be as long as 2 m—for example, the axons that originate in your spinal cord and terminate in the muscles of your toes. Small membrane-enclosed vesicles carrying materials essential to axonal function move along microtubules of the cytoskeleton, from the cell body to the tips of the axons. If the average velocity of a vesicle is 1 μm/s, how long does it take a vesicle to move from a cell body in the spinal cord to the axonal tip in the toes?Because the plasma membrane is selectively permeable, nothing can diffuse through the bilayer. True or False
- Chloride ions (Cl-) are in higher concentration outside of the cell compared to the intracellular fluid (ICF). If a cell is at rest and chloride-specific ion channels open, identify what would happen. Choose ALL of the correct answers. 1 Some chloride will enter the cell, but the concentration gradient for chloride will not change much. 2 The membrane will hyperpolarize 3 Chloride will come into the cell until it reaches chemical equilibrium. 4 The membrane potential won't change. 5 The membrane will depolarize 6 Some chloride will leave the cell, but the concentration gradient for chloride will not change muchThe non polar portion of the plasma membrane are composed of: phosphate headgroups phosphate tails fatty acid headgroups fatty acid tailsHow exactly does a cell's plasma membrane work? I have a vague understanding of it, but I would like a better explanation. Thanks.
