- Eukaryotic cell membranes function as a hydrophobic barrier around the cell and prevent the passage of polar or charged molecules. Briefly explain how cell membranes work and use a simple diagram to aid your explanation. Refer specifically to hydrophobic and hydrophilic components in their structure.arrow_forwardWhich is true about the phospholipid membrane? Group of answer choices: A. It is made up of phospholipid molecules which have a hydrophilic tail and a hydrophobic head B. It is made up of 4 layers of phospholipid molecules C. It is made up of phospholipids, which have a hydrophilic head and a hydrophobic tail D. It is made up mostly of proteins but has cholestrol molecules and phospholipids embedded within itarrow_forwardWhen a water droplet is placed in an oil solution, the phospholipids will form a micelle as shown. Explain why the phospholipids become organized in this way. Oil Waterarrow_forward
- Explain the following statement: The structure of all biomembranes depends on the chemical properties of phospholipids, whereas the function of each specific biomembrane depends on the specific proteins associated with that membrane.arrow_forwardWhat is an example of a phospholipid bilayer?arrow_forwardGive an example of a phospholipid bilayer?arrow_forward
- The cells of plant seeds store oils in the form of droplets enclosed by membranes. Unlike the membranes you learned about in this chapter, the oil droplet membrane consists of a single layer of phospholipids rather than a bilayer. Draw a model for a membrane around an oil droplet. Explain why this arrangement is more stable than a bilayer.arrow_forwardThe image shows a lipid bilayer, with the polar heads represented by circles and the hydrophobic tails represented by lines. Arrange the fatty acids in the lipid bilayer to indicate a structure that, when incorporated into a phospholipid, would result in a more fluid membrane with a lower melting point. Be sure to insert the fatty acids into the bilayer in the correct orientation. Not all the fatty acids will be used.
