Step by step
Solved in 2 steps
- Examine the following structure. Fatty acid Fatty acid PO Alcohol Which of the following is the correct classification of this substance? All of these are correct classifications. glycerophospholipid phospholipid complex lipid GlycerolWhich of the following describes how regions of phospholipids are arranged in the cell membrane? Hydrophobic fatty acid regions are positioned toward polar environments. Hydrophilic phosphate regions are positioned toward nonpolar environments. Hydrophilic phosphate regions face each other within the interior of the cell membrane. Hydrophobic fatty acid regions face each other within the interior of the cell membrane.Lipid bilayers form spontaneously in a process driven by the hydrophobic effect. Explain how the hydrophobic effect drives bilayer formation from individual lipids in an aqueous environment. Describe how the physical properties of the lipid bilayer are determined by the chemical properties of the membrane lipid components. Diagrams are encouraged for both parts of the question.
