Sort the descriptions into properties that describe either saturated phospholipids or unsaturated phospholipids.Saturated phospholipidshave straight fatty acid tailshave no double bonds in the fatty acidcarbon chainsfatty acid tails pack tightly togetherproduce a fairly inflexible membrane atlow temperaturesSaturated andunsaturated phospholipidsmaintain some space betweenadjacent phospholipidsare built upon a glycerol backboneAnswer BankUnsaturated phospholipidshave bent fatty acid tailscontain one or more double bonds within thefatty acid tailsallow the membrane to remain fluid andflexible at low temperatures

Which of the following descriptions is the best for a phospholipid? A polar lipid molecule that fully repels water through all its parts A lipid molecule that consists of two fatty acids, glycerol and a phosphate group and is amphipathic A polar lipid molecule that is made nonpolar by the addition of a phosphate group O A polar lipid molecule that fully interacts with water O A nonpolar lipid molecule that is made fully polar by the addition of a phosphate group so it can interact with water
A phospholipid can be used to do all the following except O Increase the fluidity with the presence of unsaturated fatty acid tails. create a bi-layer membrane using amphipathic properties. form a micelle using a single layer and a hydrophobic core. O connect to a glycerol molecule to create a triacylglyceride.
Cholesterol is an integral part of plasma membranes. Based on its structure, where is it found in the membrane? O within the tail bilayer O on the extracellular surface O embedded with the phospholipid heads O attached to the intracellular surface
select the false statement regarding phospholipid bilayer membranes. phospholipid bilayer part of the biological membrane has to be highly fluid to support its biological function. One of the forces driving phospholipid aggregation are Vender Waals interaction. Aggregation of phospholipid molecules is favored by higher entropy of water molecules in the aggregated state. Fluidity of phospholipid membranes is lower with higher content of unsaturated fatty acids. Phospholipid membrane containing unnatural trans unsaturated fatty acid are more rigid.
which is true of a phospholipid? O the fatty acid tails are hydrophilic and repel water O the fatty acid tails are hydrophobic and repel water O the entire phospholipid is hydrophilic and repels water O the glycerol heads are hydrophilic, and repcl water
Explain the different properties of the head and tails of phospholipids (polar, hydrophilic, nonpolar, hydrophilic)
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
Sphingolipids are considered as phospholipids if: O The polar head group contains a single sugar (carbohydrate) such as glucose All sphingolipids are phospholipids O The polar head group contains a phosphate group The polar head group contains a complex sugar (carbohydrate) containg sialic acid
Which of the following are proteins? O cholesterol O ion channels O phospholipids O glycolipids O none of the above
Which of the following is a true statement? Sphingolipids contain 2 hydrophobic, acyl chains Phospholipids contain 3 hydrophobic acyl chains Sphingolipids are completely no-polar, hydrophobic molecules The different types of phospholipids do not have different physical properties when in the membrane
phospholipid bilayer O protein 10 O cholesterol n protein cholesterol Using the diagram above, which component of this membrane contains a hydrophobic region and acts as the primary barrier to most foreign substances" carbohydrate chain carbohydrate chain Ophospholipid bilayer
The composition of a cell membrane is not uniform for all types of cells.Some cell membranes are more rigid than others. Rigidity is determinedby a variety of factors, one of which is the structure of the carbon chains in the phospholipids that comprise the membrane. One example of aphospholipid was drawn, and another, having C–C double bonds in its carbon chains, is drawn here. Which phospholipid would be present in the more rigid cell membrane and why?
