4. Which statement about membrane phospholipids is not true?a. They associate to form bilayers.b. They have hydrophobic “tails.”c. They have hydrophilic “heads.”d. They give the membrane fluidity.e. They flip-flop readily from one side of the membrane to the other

Which statements describe the characteristics of phospholipids?Question 13Answera.Part of the molecule is hydrophobic.b.They are the primary components of cell membranes.c.They form a bilayer when placed in water.d.The tails of the molecule are hydrophilic.e.The tails congregate in the middle.

Which of the following is false about the phospholipids in the cell membrane?Phospholipids of the bilayer have one fatty acid and a phosphate group.Phospholipids of the bilayer have two fatty acids and a phosphate group.Phospholipids of the bilayer always have hydrophilic phosphate heads.Phospholipids of the bilayer always have a hydrophobic tail.

Which of the following Incorrectly describes the Phospholipid bilayer?Proteins embedded in the bilayer facilitates transport of substances.Phospholipids associates to form two layersThe hydrophobic tails are pointed outward.The hydrophobic tails are pointed inward.

Phospholipids are amphipathic, which means they contain components that:can only be in contact with other lipids and not waterAllow a cell to be recognisedcan only be in contact with water and not lipidscan be in contact with water and components that prefer to be in contact with lipids.

Which of the following describes how regions of phospholipids are arranged in the cell membrane?Choose 1 answer:Choose 1 answer:(Choice A, Checked)   Hydrophobic fatty acid regions are positioned toward polar environments.AHydrophobic fatty acid regions are positioned toward polar environments.(Choice B)   Hydrophilic phosphate regions face each other within the interior of the cell membrane.BHydrophilic phosphate regions face each other within the interior of the cell membrane.(Choice C)   Hydrophilic phosphate regions are positioned toward nonpolar environments.CHydrophilic phosphate regions are positioned toward nonpolar environments.(Choice D)   Hydrophobic fatty acid regions face each other within the interior of the cell membrane.DHydrophobic fatty acid regions face each other within the interior of the cell membrane.
