Which of the following statements is/are incorrect?1. The cell membrane is purely hydrophobic.2. Glycerophospholipids have a phosphate derivative group that is known as the polar head group.3. The individual glycerophospholipid molecules that aggregate become covalently linked to each other to form a lipid bilayer.4. The interfacial region of a lipid bilayer is polar due to the polar head groups of the lipid molecules that make up the bilayer.O 1 and 3O 1 onlyO 2 and 4O 3 onlyO 4 only

1) Placing phospholipids in water will spontaneously form a spherical structure called a:Group of answer choices lumen ball sphingoid cytoskeleton liposome 2) Saturated fatty acidsGroup of answer choices Have each carbon "saturated" with hydrogen Have each carbon "saturated" with other carbons Have each carbon "saturated" with hydrogen and are solids at room temperature Are solids at room temperature Contain double bonds 3) In intestinal epithelia, glucose can be taken into cells against its concentration gradient. How can glucose be transported against its concentration gradient without the direct expenditure of ATP in intestinal epithelial cells?Group of answer choices It uses simple diffusion It uses the Glut1 transporter It uses the Glucose ATPase It uses the Glucose/Na+ symporter None of the above. Due to the Second Law of Thermodynamics, molecules cannot be moved against their concentration gradient.
Choose the best answer 1) If the lipid bilayer in Section B represents the plasma membrane, which part of the protein is the cytoplasmic domain? There is no way to tell which is the cytoplasmic domain with the information given. Section A is the cytoplasmic domain since it contains disulfide bonds. Section C is the cytoplasmic domain since the N-terminus is always found in the cytoplasm. Section C is the cytoplasmic domain since glycosylation cannot occur on the cytoplasmic domain. Section B is the cytoplasmic domain since it is an alpha-helix. 2) Which type of amino acids is most commonly found in Section B? Hydrophilic Hydrophobic There is no way of knowing which type of amino acids is most commonly found in Section B with the given information Charged 3) If the lipid bilayer in Section B represents the ER membrane, which part of the protein is found INSIDE the ER (in the ER lumen)? The entire protein must be inside the lumen of the ER. Section C is inside the ER…
Define the following terms: a. lipid bilayer b. fluid mosaic model c. membrane fluidity d. flippase e. floppase
What chemical property characterizes the interior of the phospholipid bilayer? O hydrophilic O hydrophobic saturated O polar
Consider the following diagram of the cell membrane. Which of the statements is NOT true regarding the cell membrane? Group of answer choices a. Proteins and carbohydrates are also components of the cell membrane. b. Certain phospholipids and proteins on the outer surface of the cell membrane are attached to carbohydrates. c. Some carbohydrates extend through the entire lipid bilayer and appear on both surfaces of the membrane d. Some of the proteins embedded in the cell membrane constitute channels (passage canals).
If you place phospholipids in an oil-based solution, would they still self-assemble into a bilayer? If so, describe its structure.
Which statement is NOT correct concerning the cell membrane? 1. The fatty acid hydrophobic "tails" are contained within what becomes a double- layered molecule. 2. This molecule provides an impermeable barrier for the cell from the watery outer environment. 3. The overall structure of the cell membrane results from the amphiphilic phospholipid molecules. 4. Because of the hydrophilic property of the phosphate containing "head", this "head* orients itself toward the "watery." cytoplasm and the extracellular fluid.
