Which is a characteristic of the phospholipids in cell membranes? Select one: O Phospholipids in a membrane interact with other membrane molecules, in part, through covalent forces O Phospholipids in a membrane interact with other membrane molecules through non-covalent forces O Increasing the proportion of protein in a membrane increases the amount of membrane symmetry O Increasing the proportion of saturated fatty acids in a membrane increases membrane fluidity O A phospholipid molecule glows in the dark after exposure to visible light

What chemical property of phospholipids is key to the formation ofthe cell membrane?a. The positively charged nitrogen atomb. The covalent bond between the phosphate and the glycerolc. The kink in the fatty acid taild. The hydrophilic head and hydrophobic tails
How do phospholipids interact with water molecules? Phospholipids do not interact with water because water is polar and lipids are nonpolar. The polar heads interact with water; the nonpolar tails do not. The polar heads avoid water; the nonpolar tails attract water (because water is polar and opposites attract). Phospholipids dissolve in water.
Which One is NOT TRUE about membranes? a. Membranes rich in fatty acids containing one or more double bonds are more fluid than membranes with no double bonds in fatty acids. b. If cholesterol is present in membranes, the fluidity of membranes will be reduced at moderate and warm temperatures. c. If cholesterol is present in membranes, the fluidity will remain intact at low temperatures. d. If the fatty acids with double bond are present in membranes, the membrane will be viscous.

What is the role of cholesterol in the cell membrane? It converts cis bonds of fatty acids to trans. It allows for the formation of micelle structures. It attracts to the polar phospholipid heads. It reduces membrane fluidity.
Which of the following molecules is not capable of forming lipid bilayers? a. glycolipids b. wax esters c. phospholipids d. cerebrosides
