- Which plasma membrane component can be either found on its surface or embedded in the membrane structure? a. protein b. cholesterol c. carbohydrate d. phospholipidThere are specific regions within the cell membrane known as cell membrane domains. Discuss cell membrane domains, their formation, and highlight their importance in cellular functions. You should use examples to elaborate.Practitioners of naturopathic medicine often use “essential oils” such as lavender oil. (Note that essential refers to their essence or scent and does not imply that these substances are necessary for health.) One of the components of lavender oil is shown below. Based on its structure, could this molecule diffuse through the cell membrane of a skin cell after the oil was applied to the skin surface?
- Which electron or light microscopy technique would you use for the following? (also explain) For visualizing the fine structure of cellular organelles and cell architecture in the cell interior using very thin cross-sections made in Epon. To obtain sequential images of a macromolecule in order to study its activity in real-time. To obtain an extremely clear three-dimensional image of the nucleus of a single cell. What is the magnification of the image in a microscope using a 20x ocular and a 100x objective?The cell membrane regulates the movement of molecules in and out the cell. what other functions does the cell membrane perform?The cytoplasm of a certain cell is composed of a solution that is 98% water, 2% solutes. Consider the solution shown in the beaker in this picture: FOOE OOS Foor solution. [Select] Cytoplasm is 98% water, 2% solutes. The solution in the beaker would be considered when compared to [Select] The plasma membrane is impermeable to solutes. Beaker solution is 98% water, 2% solutes the cell. We would expect that the cell would [Select] if it was placed in the would account for whatever changes might occur to the volume of the cytoplasm of the cell when it is placed in the solution.
- CELL ENVIRONMENTS Fill in the following statement: Diffusion is the movement of molecules from_high_concentration to_low. concentration. is the diffusion of water. BEAKER #I The solution inside the beaker is: % water % salt The solution inside the cell is: 90 10 % water % salt 20% salt How will the water move? Into the cell or out of the cell? 10% salt How will the movement of water affect the cell? The cell O Water molecules This is a(n) solution.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?Endoplasmic reticulum, mitochondria, and golgi bodies are structures in cell whose forms dictate their physical functions. Describe their function in relation to their structure.
