Think about the Arctic flounder that lives in cold Arctic waters and the Arabian camel that lives in hot deserts. How might these Arctic flounder and Arabian camel modify the lipid composition of their cellular membranes to withstand their respective environments? Also, how would these modifications relate to the transition temperature of the lipid bilayer? And how could such adaptations affect the function of proteins within the membrane and the overall performance of the cell?

Proteins 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?
Draw and label a cell lipid bilayer and diagram how the following transport processes take place: passive diffusion of oxygen into the cell, facilitated diffusion of potassium into the cell, active transport of sucrose into the cell. Using different symbols (circles for oxygen, squares for sucrose, and triangles for potassium ions), show the relative concentrations (gradients) of these substances on the inside and outside of the cell. For example, to show that oxygen enters the cell by going “down” its gradient, you would draw more circles on the outside of the cell than inside the cell. Be sure to show and label membrane proteins when appropriate, and show the electric membrane potential using “+”s (pluses) on one side and “-”s (minuses) on the other side of the membrane. Also show the proton pump which uses ATP as a source of energy.
What is unique about plasma membrane? Why is it advantageous for the plasma membrane to be fluid in nature? How does the sodium-potassium pump contribute to the net negative charge of the interior of the cell? In medicine, why is it important to administer only isotonic intravenous solutions to patients? Example of isotonic IV fluids are normal saline and lactated Ringer’s solution. Potassium is a necessary nutrient in order to maintain the function of our cells. What would occur to a person that is deficient in potassium?
which of the following changes in the plasma membrane of a salmon is most likely to occur as it migrates to a much colder region of the Pacific Ocean? HInt: the fluidity of the salmon's plasma membranes must remain relatively constant during its migration. The percentage of integral membrane proteins in the plasma membrane would increase The percentage of unsaturated fatty acid tails in plasma membrane phospholipids would increase The percentage of unsaturated fatty acid tails in plasma membrane phospholipids would decrease The percentage of peripheral membrane proteins in the plasma membrane would increase
Cells transporting substances across their membranes is essential. Choose TWO of the following types of cellular transport. ๏osmosis ๏active transport ๏facilitated diffusion ๏endocytosis / exocytosis (a)For each type of transport you choose, describe the transport process. Explain how the organization of cell membrane plays a role the movement of specific molecules across membrane. (b)Using the same transport types, identify a specific cell that utilizes that type of transit (i.e. one cell for each transport type, or two different cell examples), and detail a substance that is transferred. (c)A typical human lymphocyte has a radius of about 10 μm, while a typical bacterium (e.g., S. pneumoniae) has a radius of about 1 μm. Assuming that both cell types are perfectly spherical, compare and contrastthe transport mechanisms for each of these cells.
1) We measured weights before and after soaking a potato in water of different salinities to demonstrate osmosis. There are many other types of membrane transport (as we learned from the Amoeba Sisters!), each with their role in maintaining homeostasis and providing energy, communication, and waste removal for the cell. So why dwell on osmosis? There are some practical bigger- picture things to consider. Choose one of the following scenarios. Describe the scenario. Describe the chain of events terms of tonicity_and movement of water into or out of cells represented by the scenario. Describe the predicted outcomes for the cells/organisms involved. What happens when you dry brine a turkey before cooking? ● • What happens to organisms in soil near salted roads when snow melt and rains occur? Why is sugar considered a good preservative? What is the challenge of heavy rains along the Mississippi River for organisms in the Gulf of Mexico? ● • What happens to fruit when you add sugar? ●
List and describe the three main types of cytoskeleton. If you wanted to do immunocytochemistry to specifically stain each type of cytoskeleton, what is a protein that could be used for each cytoskeletal type (in other words, what is a unique protein for each cytoskeletal type)? What are three types of actin structures? Describe the involvement of actin structures in cell migration. How is the growth and shrinking of microtubules regulated? Then describe the roles of microtubules in: chromosomal separation during mitosis and the movement of organelles and vesicles within a cell. Describe a possible mechanism on how signaling pathways might impact the cytoskeleton, so that cell migration could be regulated in a localized manner within a multicellular organism. (hint: think about the possible transcriptional regulation of the G-protein regulators) What are 2 main challenges of protein targeting? Then describe one way these challenges are overcome during signal-based targeting and one way…
Which of the following statements are correct about how the complex biological matrix of the cell may affect protein folding, stability and function (select all that appy)? A. ATP tends to "bounce" along the surfaces of many proteins without forming a stable complex B. Proteins make up approximately 30% of the total volume of the cytoplasm in a typical cell C. Compettition between drug molecules and metabolites in the cytoplasm may cause unexpected drug side effects not seen with individual proteins in solution. D. Large protein complexes move faster through the cytoplasm than small metabolites. E. Complex intercations between proteins in the cell may significantly destabilize a protein compared to the isolated protein in water
The plasma membrane of E. coli is approximately 75% protein and 25% phospholipid by weight.

Why is the plasma membrane descibed as a semipermeable membrane? why are proteins required to augment the functions of hte phospholipid bilayer that forms the backbone of cell membranes? distinguish between the different types of molecular transport, why are they necessary, how do they enhance cellular functions, why are some cellualar processes free while others require the input of energy?
In the fluid mosaic model: plasma membrane proteins orient their hydrophilic sides toward the internal bilayer. phospholipids often flip-flop between the inner and outer layers. the mosaic refers to proteins attached to the underlying cytoskeleton. the fluid refers to the phospholipid bilayer. the mosaic refers to the symmetry of the internal membrane proteins and sterols.
