16. What phosphoglyceride components would be found in the interior of a cell membrane lipid bilayer? a. polar "heads" of molecules b. nonpolar "heads" of molecules O C. polar "tails" of molecules d. nonpolar "tails" of molecules

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.

Below is the skeletal formula of a molecule typically found in cell membranes. What type of molecule is this and how can you tell? What are the functions of this type of molecule in the plasma membrane of a cell? CH3 CH₂) (CH₂) 16 CH3 Ko

For biological membranes, which of the following statement is NOT true? A. The phospholipid bilayer is a fluid matrix. B. Protein can be anchored to the membrane by covalently linked lipid chains. C. Proteins can move laterally across the membrane. D. For organisms living in cold temperature, their cell membranes contain more triacylglycerols. E. Transverse motion of lipid molecules can occur occasionally.   Enzyme lowers when... A. The energy difference between the substrate and the transition state B. The energy difference between the product and the transition state C. Both A and B D. Neither A nor B
