Question

Which of the following statements is not supported by the fluid mosaic model? a. The major structural component of the plasma membrane is a phospholipid bilayer. b. Cholesterol is a "fluid" part of the model because it is found in the interior of the plasma membrane due to its hydrophobicity. c. Peripheral glycoproteins on the extracellular surface play a role in structural support. d. Membranes with a higher ratio of saturated fatty acids are less fluid. e. Some integral proteins have enzymatic activity. f. Some integral proteins help connect the ECM to the cell and transmit signals across the membrane. QUESTION 2 Which of the following accurately describes transmembrane proteins? a. Hydrophilic regions of transmembrane proteins are found on the interior of the membrane. b. Transmembrane proteins are included in the fluid part of the fluid mosaic model. c. Membrane-spanning regions of some transmembrane proteins include hydrophilic channels. d. Extracellular regions of transmembrane proteins are typically polar. e. Integral and peripheral proteins are two types of transmembrane proteins. f. Transmembrane proteins on the cytoplasmic side of the membrane have polar nucleic acids. g. A-B only h. C-D only i. D-F only j. A-F only
