Textbook Question
Chapter 3, Problem 8CHI
LPS is synthesized in the cytoplasm and then transported to and inserted into the outer membrane. This is complicated by the amphipathic nature of LPS. Recently two different laboratories reported their studies on seven LPS transport proteins (Lpt proteins) that move LPS from the cytoplasm into the outer membrane. Several of the Lpt proteins fold to form a structure called a β-jelly roll, which can be described as being “greasy.” Other Lpt proteins fold to form a β-barrel. Hypothesize how each fold might interact with an LPS molecule. Why would two different types of proteins be needed?

- The figure above shows the organization of a protein that will eventually reside in the plasma membrane. The boxes labeled 1 and 2 represent membrane-spanning sequences and the arrow represents a site of action of signal peptidase. Which of the following statements must be TRUE about this protein? O a) Most of this protein will project from the cytosolic side of the membrane. O b) The mature version of this protein will span the membrane twice. c) This is a multi-pass membrane protein. O d) The mature version of this protein will span the membrane once.arrow_forwardProteins may be bound to the exoplasmic or cytosolic face of the plasma membrane by way of covalently attached lipids. What are the three types of lipid anchors responsible for tethering proteins to the plasma-membrane bilayer? Which type is used by cell-surface proteins that face the external medium? By glycosylated proteoglycans?arrow_forwardOne thousand Ca2+ channels open in the plasma membrane of a cell that is 1000 μm3 in size and has a cytosolic Ca2+ concentration of 100 nM. for how long would the channels need to stay open in order for the cytosolic Ca2+ concentration to rise to 5 μm? There is virtually unlimited Ca2+ available in the outside medium (the extracellular Ca2+ concentration in which most animal cells live is a few millimolar), and each channel passes 106 Ca2+ ions per second.arrow_forward
- Ribosomes in the cytoplasm (cytosol) capture mRNA that can be translated into an enzyme (in this case a protease) to the lysosome. a) Describe what happens from the time the enzyme (protease) begins to form in the cytoplasm until it end up in the lysosome and explain how the enzyme is transported to the lysosome, Explain in terms of the clathrin and thethering proteinsarrow_forwardHistamine acts by binding to specialized membrane proteins called histamine H 1 receptors. These receptors, found in specific cells, are integral membrane proteins that possess seven transmembrane a-helical regions. The amino terminus of the protein is extracellular, while the C-terminus is cytoplasmic. The binding of histamine to the extracellular portion of the H 1 receptor prompts a conformational change in the intracellular C-terminus region of the protein. This conformational change triggers numerous intracellular signaling events that stimulate the immune response in cells containing the receptor. There are numerous anti-histamine drugs available commercially. Some of the most popular are shown here side by side with histamine: HCHS NH- Allegra H2N histamine Claritin Propose a reasonable mode of action by which these antihistamines exert their activity. Include relevant details about the system of your own choosing.arrow_forwardMany biological tissues have layers with extracellular matrix components and different orientations of these components. As a result, diffusion coefficients vary from region to region. Consider the steady-state, one-dimensional diffusion of a protein across a tissue that consists of a cellular phase and an acellular phase (like an artery wall consisting of a layer of smooth muscle cells and a layer of elastic lamina. Assume no reactions occur in either layer. The protein diffusion coefficients in the layers (1 and 2) are Di,1 and Di,2. The concentration at one edge is (x = 0) Ci = C0; on the other edge (x = L1 + L2 = L) Ci = CL. Assume that all partition coefficients in both layers are equal to 1. Use the figure below to help. Determine (A)the concentration as a function of position x, (B) the flux of the protein solute across the tissue, and (C) the effective diffusion coefficient if the system is modeled as a single layer.arrow_forward
- A cell with a K+1 concentration of 0.3 eq/L, and a Na+1 concentration of 0.1 mol/L is placed into a solution with a K+1 concentration of 0.2 eq/L, and a Na+1 concentration of 0.2 mol/L. It is assumed that the K+1 and Na+1 can both pass through the cell membrane (the K+1 and Na+1 transport proteins are open). Answer the following true or false questions. 1. Diffusion of a solute through the membrane is called dialysis 2. K+1 will dialyze (diffuse) out of the cell 3. Na+1 will dialyze (diffuse) into the cell 4. Like the diffusion of gases, diffusion of particles in a liquid is independent of the other solutesarrow_forwardGaucher disease, caused by the inhibited digestion of lipids, results in the accumulation of fatty acids within many organs in the body and leads to their subsequent dysfunction. Which of the following describes the most likely subcellular component and related process responsible for the development of Gaucher disease? A B с D Lysosomes contain insufficient amounts of enzymes necessary for the metabolism of lipids. The Golgi complex produces vesicles with highly permeable membranes that cannot ef- fectively regulate the movement of particles. Mitochondria are not producing a sufficient amount of ATP required for the digestion of lipids. The rough endoplasmic reticulum contains an unusually high number of ribosomes, re- sulting in an overproduction of digestive enzymes.arrow_forwardRibosomes in the cytoplasm (cytosol) capture mRNA that can be translated into an enzyme (in this case a protease) to the lysosome. a) Describe what happens from the time the enzyme (protease) begins to form in the cytoplasm until it end up in the lysosome and explain how the enzyme is transported to the lysosome.arrow_forward

These molecules are often clustered side-to-side to create a form of molecular Velcro that attaches one cell to another cell or to the extracellular matrix. In the following drawings, two cells are initially attached via such a Velcro. When one of the cells moves in either of three different ways (A to C), it is faced with a mechanical resistance from the cadherin interactions. The resistance against which type of movement do you think is the weakest? Two neighboring cells D. The cell moves away from its neighbor A. Two neighboring cells B. The cell moves away from its neighbor OC. The cell slides past its neighbor D. The cell rolls over its neighbor The cell slides past its neighbor C The cell rolls over its neighborarrow_forwardRibosomes in the cytoplasm capture mRNA that can be translated into an enzyme for the lysosome. a) Explain what happens from the time the enzyme begins to form in the cytoplasm until it ends up in the lysosome and also explains how the enzyme is transported to the lysosome?arrow_forward
