- Why do you think a Medical Technologist should know the basics of Osmosis, Diffusion and Emulsification processes?Define each of these terms: a freely permeable membrane, an impermeable membrane, and a selectively permeable membrane. During your next exam, you may begin to sweat a solution of sodium, chloride, and water, but not proteins, sugars, or nucleotides. Are the membranes of your sweat gland cells freely permeable, impermeable, or selectively permeable?Why the composition of biological membrane varies ? Should it be helpful in membrane physiology ?
- A solution of water and dissolved ions is separated by a selectively permeable membrane that allows the passage of water but not small ions. The concentration of sodium is higher on one side of the membrane than onthe other side. However, there is no net movement of water across the membrane. How is this possible?Using the answer code on the right, indicate which membrane component is responsible for the function in question: 1. channel formation____________________________________ (a) lipid bilayer 2. barrier to passage of water- __________________ (b) proteins soluble substances ____________________________________ (c) carbohydrates 3. receptor sites 4. membrane fluidity 5. recognition of self 6. membrane-bound enzymes 7. structural boundary 8. carriersFish Cell Physiology Compare and contrast the movement of salt ion in the tissues of a living fish and the tissue of a dead fish, is it similar? What goes in and goes out of the cell? Is it water or salt, discuss in both the living and the dead fish. Discuss what particular part of the cell and the mechanism of this process.
- How do cellular osmosis takes place from interstitial fluid to the vacuole and vice versa? please help asapDescribe the general structure of all cell membranes. How does this membrane structure determine the selective permeability of what can pass across the membrane. Then describe 3 ways cell membranes will differ from one another.THE PERMEABILITY OF THE CELL MEMBRANE: 1. Three eggless shells were used. Please answer the tables shown in the image provided,
- Left Compartment Right Compartment 7 grams of Z per liter solution 4 grams of XY per liter of solution total volume = 1 liter total volume = 1 liter Solute Z has a molecular weight of 20 (non-dissociable) Solute XY has a molecular weight of 10 (dissociates into X+ and Y-) If X+ and Y- are ions, which are permeable through the membrane, and Z is not, what will happen and why?You were introduced to osmosis in Chapter 8 earlier in the course. This week, Chapter 15 continues this discussion by introducing the cell membrane. For additional information, review one or two of the websites listed below. Osmosis: Real-life Applications How Is Osmosis Used in Kidney Dialysis? Guide to Forward Osmosis Applications Choose one way that osmosis and membranes are used in living things, medicine or industry. Describe how osmosis and membranes are used in the real-life application you chose. What are some of the materials necessary? Is an input of energy necessary?Urgent help needed Watch the following movie clip from Lord of the Rings: The Fellowship of the Ring. In this clip, Gandalf the Wizard stops the fire demon from passing across the stone bridge. Explain how this clip is similar to the role of the plasma membrane. Use as much detail (about the membrane, not the movie) to support your answer.
